The metal atom in the anion of the title salt, (C(7)H(11)N(2))(2)[CuBr(4)], shows a distorted tetra-hedral coordination. The primary contacts between the ions are of the N-H⋯Br type.
The reaction of a cobalt(II) salt with 4-(dimethyl-amino)pyridinium hydro-bromide perbromide yielded the title compound, (C(7)H(11)N(2))[CoBr(3)(C(7)H(9.1)Br(0.9)N(2))]. In the anion, the Co(II) atom is coordinated in a distorted tetra-hedral geometry by three Br atoms and the pyridine N atom of a bromine-substituted 4-(dimethyl-amino)pyridine mol-ecule, whose formation probably results from an incomplete substitution (90%) catalysed by the Co(II) ion. One of the three bromine atoms bonded to the metal is disordered over two sites in a 0.9:0.1 ratio. An N-H⋯Br hydrogen bond connects the cation and anion.
The Pd(II) atom in the title compound, [PdBr(2){P(C(6)H(5))(3)}(2)]·CHCl(3), lies on a twofold rotation axis and is coordinated in a distorted square-planar geometry by two P atoms from two triphenyl-phosphine ligands and by two Br atoms in a trans arrangement. The chloro-form solvent mol-ecule is equally disordered about another twofold rotation axis.
The metal atom in the title salt, (C(7)H(11)N(2))(2)[CoBr(4)], shows a slightly distorted tetra-hedral coordination. The cation forms an N-H⋯Br hydrogen bond to one of the two Br atoms. The Co(II) atom lies on a special position of 2 site symmetry.
The Sn(IV) atom in the title salt, [N(CH(3))(3)(C(6)H(5))](2)[SnBr(4)(C(6)H(4)Cl)(2)], exists in a distorted all-trans SnC(2)Br(4) octa-hedral geometry. The Sn(IV) atom lies on a center of inversion. Weak inter-molecular C-H⋯Br hydrogen bonding is observed between trimethyl-phenyl-ammonium cations and the Sn complex anion in the crystal structure.
The tin atom in the substituted ammonium stannate(IV), (C(5)H(6)N)(2)[SnBr(3)(C(6)H(4)Cl)(2)Cl], lies on a center of symmetry in a distorted octa-hedral coordination geometry. Each independent halogen site is occupied by bromine and chlorine anions in an approximate 3:1 ratio. The pyridinium cation forms a hydrogen bond to only one of the halogen atoms.
The carbonyl unit of the title compound, C(13)H(10)Cl(2)N(2)O, lies on a twofold rotation axis. The ring is aligned at 51.6 (1)° with respect to the N-C(=O)-N fragment. The two -NH- fragments of one mol-ecule form hydrogen bonds [2.845 (2) Å] to the C=O fragment of an adjacent mol-ecule, giving rise to the formation of a linear hydrogen-bonded chain.
The title polymeric mixed-organyl tin hydroxide, [Sn(C(6)H(5))(2)(C(6)H(11))(OH)](n), hass a hydroxide-bridged chain structure; the tin center shows trans-C(3)SnO(2) trigonal bipyramidal coordination. The Sn atom lies on a special position of site symmetry m; the symmetry element relates one phenyl ring to the other and also relates one half of the cyclo-hexyl ring to the other half.
The Sn atom in the title compound, [Sn(C(5)H(9))(C(6)H(5))(2)(C(6)H(10)N(3)O(2)S)], exists within a tetra-hedral geometry. The -NH(2) group forms a weak hydrogen bond across a center of inversion to the S atom of an adjacent mol-ecule, as well as another weaker hydrogen (across another center of inversion) to the Sn-bound O atom of another mol-ecule. The hydrogen-bonded layer structure is consolidated by a strong hydrogen bond between the -NH- group and the uncoordinated O atom of a third mol-ecule.
The tin(IV) atom in the salt, (C(7)H(11)N(2))(2)[SnBr(2)(CH(3))(2)Cl(2)], lies on a center of inversion in a tetra-gonally compressed octa-hedron; the bromine atoms are disordered with the chlorine atoms, so that they appear to share the same site. The crystal structure is stabilized by N-H⋯Br hydrogen bonds.
The Pb(IV) atom of the anion of the title salt, (C(7)H(11)N(2))(2)[PbBr(4)(C(6)H(5))(2)], is situated on a crystallographic center of inversion and exhibits a tetra-gonally compressed octa-hedral coordination. One of the two independent Br atoms acts as a hydrogen-bond acceptor towards the NH group of the cation.
In the title compound, C(12)H(24)N(+)·Br(-), both cyclo-hexane rings adopt the usual chair conformation. The cation and anion are linked by N-H⋯Br hydrogen bonds into a linear chain running along the c axis.
The Pb(IV) atom of the plumbate dianion in the title compound, (C(7)H(11)N)(2)[Pb(Br(3.75)Cl(0.25))(C(6)H(5))(2)], lies on a centre of inversion in a tetra-gonally compressed octa-hedral geometry. One of the attached Br atoms is disordered with respect to a Cl atom in a 7:1 ratio. The disordered halogen atom is an N-H⋯(Br/Cl) hydrogen-bond acceptor for the cation.
The asymmetric unit of the title compound, [Ag(2)(C(2)ClF(2)O(2))(2)(C(25)H(22)P(2))(2)], consists of two half-mol-ecules, each Ag(I) ion lying on a center of symmetry. In each complete mol-ecule, two bis-(diphenyl-phosphino)methane ligands bridge two Ag(I) ions, which are further coordinated by one chloro-difluoro-acetate ligand, giving T-shaped geometries and short intra-molecular Ag⋯Ag distances of 3.1078 (6) and 2.9950 (6) Å. In one mol-ecule, the unique -CF(2)Cl group is rotationally disordered over two sites with approximate occupancies of 0.53 and 0.47 for the major and minor components, respectively.
The chloride and chloro-difluoro-acetate anions occupy cis positions in the octa-hedral coordination geometry of the title compound, [Mn(C(2)ClF(2)O(2))Cl(C(12)H(8)N(2))(2)]. The two N-heterocycles both chelate the metal atom.
The imino-diacetic acid component of the title salt, C(4)H(8)NO(4) (+)·C(7)H(7)SO(3) (-), is protonated at the N atom. The cation uses the ammonium group to form hydrogen bonds to the O atoms of two adjacent sulfonate groups. In addition, the carboxylic acid portions of the cation form hydrogen bonds to the sulfonate groups. The hydrogen-bonding inter-actions give rise to a layer structure.
The Sn(IV) atom in the title salt, (C(7)H(11)N(2))(2)[SnBr(3)(CH(3))(2)Cl], lies on a center of inversion in a tetra-gonally compressed octa-hedron; two independent Br atoms share the same site as two independent chlorine atoms so that the anion effectively has one Cl and three Br atoms. The occupancies of the Br atoms are 0.721 (1) and 0.779 (1), and those of the Cl atoms are 0.279 (1) and 0.221 (1). The crystal structure involves N-H⋯halogen hydrogen bonds.
The title stannoxane is a toluene-solvated dimer, [Sn(4)(C(7)H(6)Cl)(8)Cl(2)O(2)(OH)(2)]·C(7)H(8), the tetra-nuclear mol-ecule lying across a center of inversion. The Sn(4)O(4) framework, whose two independent Sn atoms show trigonal bipyramidal coordination, is essentially planar (r.m.s deviation = 0.02 Å). One of the two chloro-benzyl groups of the chloridodiorganyltin unit is disordered over two positions with the chloro-phenyl residue refined over two positions in a 50:50 ratio. The solvent mol-ecule is disordered about a twofold axis.
In the mol-ecule of the title compound, C(14)H(12)N(2)O(4), the two benzene rings make a dihedral angle of 84.53 (8)°. O-H⋯O and N-H⋯O hydrogen bonds link adjacent mol-ecules into a layer structure.
In the title carboxyl-ate-bridged polymer, [Sn(C(7)H(7))(3)(C(7)H(5)O(3))](n), the Sn(IV) atom exists in a distorted trans-C(3)SnO(2) trigonal-bipyramidal geometry. The polymer propagates as a chain along the a axis. There are two independent formula units in the asymmetric unit; the furyl ring of one of the anions is disordered over two positions in a 0.630 (8):0.370 (8) ratio. The crystal studied was a non-merohedral twin with a minor twin domain of 37.3 (1)%.
