Bis(cyclo-hexyl-ammonium) tetra-chlorido-(oxalato)stannate(IV).

ABSTRACT: The title salt, (C6H14N)2[Sn(C2O4)Cl4], was obtained as a by-product from the reaction between 2C6H14N(+)·C2O4 (2-)·1.5H2O and SnCl2·2H2O. The cyclo-hexyl-ammonium cation has a chair conformation. The complex anion consists of an oxalate anion chelating the SnCl4 moiety, resulting in a distorted octa-hedral coordination sphere of the Sn(IV) atom with the O atoms in equatorial cis positions. In the crystal, cations and anions are linked through N-H?O and N-H?Cl inter-actions into a layered arrangement parallel to (100).

Bis(cyclo-hexyl-ammonium) tetra-chlorido-diphenyl-stannate(IV).

Project description:The title compound, (C6H14N)2[Sn(C6H5)2Cl4], contains cyclo-hexyl-ammonium cations in general positions and a stannate(IV) anion that is located on a twofold rotation axis. The Sn(IV) atom in the complex anion is surrounded by four Cl(-) ligands and two trans-phenyl groups in a distorted octa-hedral configuration. The anions are connected with the cations through N-H?Cl hydrogen bonds. Every cation is involved in three N-H?Cl bonds to the chloride ligands of three different anions, and each chloride ligand is linked to two cations. This arrangement leads to a layered structure parallel to (010).

Bis(trimethyl-ammonium) tetra-chlorido-diphenyl-stannate(IV).

Project description:The title compound, [(CH(3))(3)NH](2)[Sn(C(6)H(5))(2)Cl(4)], consists of [(CH(3))(3)NH](+) cations and [SnPh(2)Cl(4)](2-) anions in which the Sn atom, located on a centre of inversion, is bonded to four Cl atoms and two phenyl rings, giving an octa-hedral geometry with the phenyl rings in trans positions. In the crystal, the cations and the anions are connected by N-H⋯Cl hydrogen bonds and C-H⋯Cl inter-actions.

Dicyclo-hexyl-ammonium bis-(chloro-difluoro-acetato-?O)cyclo-hexyl-diphenyl-stannate(IV).

Project description:In the title mixed-organyl stannate, (C(12)H(24)N)[Sn(C(6)H(5))(2)(C(6)H(11))(CClF(2)O(2))(2)], there are two cations and two anions in the asymmetric unit. Each five-coordinate Sn atom shows trans-C(3)SnO(2) trigonal bipyramidal coordination. The four Sn-O distances are approximately equal in the two independent anions. Each ammonium cation serves as a hydrogen-bond donor to two stannates, the hydrogen-bonding inter-actions giving rise to linear hydrogen-bonded chains.

Bis(dicyclo-hexyl-ammonium) ?-oxalato-?O,O:O,O-bis-[aqua-(oxalato-?O,O)diphenyl-stannate(IV)].

Project description:The structure of the title compound, (C(12)H(24)N)(2)[Sn(2)(C(6)H(5))(4)(C(2)O(4))(3)(H(2)O)(2)], consists of a bischelating oxalate ion, located on an inversion center, which is linked to two SnPh(2) groups. The coordination sphere of the Sn(IV) ion is completed by a monochelating oxalate anion and a water mol-ecule. The Sn(IV) atoms are thus seven-coordinated. The discrete binuclear units are further connected by hydrogen bonds, leading to a supra-molecular crystal structure. The asymmetric unit contains one half dianion and one (Cy(2)NH(2))(+) cation.

Tetra-butyl-ammonium butyl-tetra-chlorido-stannate(IV).

Project description:In the title compound, [N(C4H9)4][Sn(C4H9)Cl4], the Sn(IV) atom of the stannate anion has a trigonal-bipyramidal coordination sphere by two Cl atoms and one butyl chain in the equatorial plane and by two Cl atoms in the apical positions. Two of the four butyl chains of the tetra-butyl-ammonium cation are partially disordered, each with refined site occupancies of 0.691?(6):0.309?(6). Weak C-H?Cl hydrogen-bonding inter-actions help to consolidate the crystal packing, as well as a short Cl?Cl inter-action of 3.295?(2)?Å.

Bis(dimethyl-ammonium) tetra-chlorido-dimethyl-stannate(IV).

Project description:Regular crystals of the title compound, (C(2)H(8)N)(2)[Sn(CH(3))(2)Cl(4)], were obtained by reacting SnMe(2)Cl(2) with (CH(3))(2)NH·HCl in ethanol in a 1:1 ratio. The Sn atom lies on a center of symmetry and is six-coordinated. It has a distorted octahedral SnC(2)Cl(4) environment with the Cl atoms in cis positions. The Cl atoms are connected to dimethyl-ammonium cations through N-H?Cl hydrogen bonds, forming an infinite chain extending parallel to [010].

The NH(2) groups of the cations act as hydrogen-bond donors to two symmetry-related anions, resulting in the formation of linear chains. One of the phenyl rings is disordered over two sites with equal occupancies.

Bis(diisopropyl-ammonium) hexa-chlorido-stannate(IV).

Project description:The title compound, (C(6)H(16)N)(2)[SnCl(6)], crystallizes with one diisopropyl-ammonium cation lying on a general position and the hexa-chloridostannate(IV) anion about a centre of inversion. The [SnCl(6)](2-) anion undergoes a slight distortion from octa-hedral symmetry as the result of the formation of four unforked charge-supported N-H?Cl hydrogen bonds. The hydrogen bonds between the cations and anions form layers perpendicular to [101]. These layers are built by 24-membered rings which can be classified with an R(8) (8)(24) graph-set descriptor. According to this hydrogen-bonding motif, the title compound is isostructural with (C(6)H(16)N)(2)[IrCl(6)].

Tris(cyclo-hexyl-ammonium) cis-di-chlorido-bis-(oxalato-?(2) O (1),O (2))stann-ate(IV) chloride monohydrate.

Project description:The crystal structure of the title compound, (C6H14N)3[Sn(C2O4)2Cl2]Cl·H2O, contains three cyclo-hexyl-ammonium cations, one stannate(IV) dianion, one isolated chloride anion and one lattice water mol-ecule. The cyclo-hexyl-ammonium cations adopt chair conformations. In the complex anion, two bidentate oxalate ligands and two chloride anions in cis positions coordinate octa-hedrally to the central Sn(IV) atom. The cohesion of the mol-ecular entities is ensured by the formation of N-H?O, O-H?O, O-H?Cl and N-H?Cl inter-actions involving cations, anions and the lattice water mol-ecule, giving rise to a layer-like arrangement parallel to (010).

Dicyclo-hexyl-ammonium trimethyl-bis-(hydrogen phenyl-phospho-nato)stannate(IV).

Project description:In the title compound, (C(12)H(24)N)[Sn(CH(3))(3)(C(6)H(6)O(3)P)(2)], the SnMe(3) residues are axially coordinated by two monodentate [PhPO(3)H](-) anions, leading to a trigonal-bipyramidal geometry for the Sn(IV) atom. The two [SnMe(3)(PhPO(3)H)(2)](-) anions in the unit cell are associated into infinite chains along the a axis by O-H?O hydrogen bonds involving the hy-droxy group of the hydrogen phenyl-phospho-nate ion. The chains inter-act with one another via O-H?O hydrogen bonds along the c axis. These networks of anions assemble with the dicyclo-hexyl-ammonium ion through N-H?O hydrogen bonds, forming a three-dimensional network.
