Project description:In the title compound, [RhCl(3)(CH(3)CN)(C(18)H(21)P)(2)]·2CH(3)CN, the complex mol-ecule lies on a twofold rotation axis that passes through the Rh(III) atom, one Cl atom, and the C and N atoms of the coordinated acetonitrile mol-ecule. The Rh(III) atom is coordinated by two P atoms in trans positions, three Cl atoms and an acetonitrile mol-ecule in a distorted octa-hedral geometry. Intra-molecular C-H⋯Cl inter-actions are observed. The uncoordinated acetonitrile mol-ecule is disordered over two sites with occupancies of 0.588 (4) and 0.412 (4).
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).
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.
Project description: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.
Project description:The five-coordinate Sn atom in the title mixed organyl stannate compound, (C(12)H(24)N)[Sn(C(5)H(9))(C(6)H(5))(2)(C(2)ClF(2)O(2))], is in a trans-C(3)SnO(2) trigonal-bipyramidal coordination environment. 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.
Project description:In the title salt, C(12)H(24)N(+)·Cl(-), both cyclo-hexyl rings adopt chair conformations and the NH(2) unit is situated in the equatorial position with respect to the rings in the cation. The large C-N-C bond angle [117.99 (14)°] in the cation is a result of linking two bulky cyclo-hexyl rings to the N atom. The aminium H atoms are involved in inter-molecular N-H⋯Cl hydrogen bonds, forming an infinite zigzag chain parallel to the c axis. The crystal studied was a racemic twin with a twin fraction of 0.28 (18).
Project description:In the title compound, C(22)H(30)NO(2)P, the P atom has an irregular tetra-hedral geometry. In the crystal, mol-ecules are connected by N-H⋯O hydrogen-bonding inter-actions, giving rise to a chain along the b axis. The phenyl ring of the anilino group is twisted by 77.40 (16)° relative to the other phenyl ring. The absolute configuration of phospho-rus is S(p).
Project description: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).
Project description:The distorted octa-hedral geometry about the Sn(IV) atom in the title compound, [Sn(C(6)H(5))(2)(C(14)H(19)N(4)S)Cl], is defined by the N,N,S-tridentate Schiff base ligand, two mutually trans ipso-C atoms of the Sn-bound phenyl groups, and the Cl atom which is trans to the azo N atom. The two five-membered chelate rings and pyridyl ring are almost coplanar with the dihedral angle between the outer five-membered chelate and pyridine rings being 5.39?(8)°. Centrosymmetric dimers feature in the crystal packing mediated by N-H?S hydrogen bonds, leading to eight-membered {?HNCS}(2) synthons. The dimeric aggregates are connected into a three-dimensional architecture by C-H?Cl and C-H?? inter-actions, as well as ?-? inter-actions occurring between centrosymmetrically related pyridine rings [centroid-centroid distance = 3.6322?(13)?Å].
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).
