Crystal structure of bis-[(5-oxo-oxolan-3-yl)triphen-ylphosphanium] hexa-iodido-tellurate(IV).

ABSTRACT: The asymmetric unit of the title salt, [C22H20O2P]2 (+)[TeI6](2-), consists of one triphenyl(5-oxooxolan-3-yl)phosphanium cation and one half of a hexa-iodido-tellurate(IV) dianion. The Te atom is located at an inversion centre and is octa-hedrally coordinated by six I atoms. The Te-I bond lengths range from 2.9255?(9) to 2.9439?(10)?Å. The I-Te-I angles between cis-iodide ligands are in the range 87.85?(3)-92.15?(3)°. In the crystal, the components are connected by C-H?I inter-actions. In the final refinement of the compound a void of 32?Å(3) was observed.

Bis(tetra-phenyl-phospho-nium) di-μ-iodido-bis[di-iodido-tellurate(II)].

Project description:The structure of the title compound, (C(24)H(20)P)(2)[Te(2)I(6)], is composed of discrete PPh(4) (+) cations and centrosymmetric [Te(2)I(6)](2-) anions. The tellurium(II) atom shows a sligthly distorted square-planar TeI(4) geometry and is coordinated to two bridging and two terminal iodine atoms. The planar [Te(2)I(6)](2-) ions are isolated by the cations and no inter-molecular tellurium-halogen or halogen-halogen inter-actions are present.

?(2)-Oxalato-bis-[triphen-yl(thio-urea-?S)tin(IV)].

Project description:The asymmetric unit of the binuclear title compound, [Sn(2)(C(2)O(4))(C(6)H(5))(6)(CH(4)N(2)S)(2)], consists of one half of the organotin(IV) mol-ecule. The remainder is generated by a twofold rotation axis passing through the mid-point of the oxalate C-C bond. The Sn(IV) atom exhibits a distorted trigonal-bipyramidal coordination environment with the phenyl groups in equatorial positions and the thio-urea and the monodentately bridging oxalate anion in axial positions. The mol-ecules are linked through N-H?O hydrogen bonds involving the amino group of the thio-urea ligand and the uncoordinating oxalate O atoms, forming layers parallel to (001). Weak C-H?O inter-actions are also present.

Triphen-yl[2-(triphenyl-phosphanium-yl)eth-yl]phosphanium bis-(periodate).

Project description:In title salt, C(38)H(34)P(2) (2+)·2IO(4) (-), the P atoms of the dication and the I atoms of the periodate anions are each in a slightly distorted tetra-hedral environment. In the dication, the two -P(C(6)H(5))(3) groups adopt a gauche conformation with respect to each other. In the crystal, several C-H?O hydrogen bonds between the cations and anions lead to a two-dimensional arrangement along (101).

Project description:In the title compound, (NH(3)C(6)H(4)CO(2)CH(3))(2)[SnCl(6)], the anions are situated on inversion centers so the asymmetric unit contains one cation and one half-anion. In the crystal, inter-molecular N-H⋯Cl and N-H⋯O hydrogen bonds link the cations and anions into layers parallel to the ac plane. The crystal packing exhibits voids of 37 Å(3).

Crystal structure of di-μ-iodido-bis-{[1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene]lithium}.

Project description:In the title binuclear complex, [Li2(C27H36N2)2I2], the unique Li(I) cation is coordinated by two iodide anions and one yl-idene C atom from a 1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene ligand in a distorted trigonal-planar geometry. The two symmetry-related iodide anions bridge two Li(I) cations, forming an inversion dimer in which the Li2I2 plane is nearly perpendicular to the imidazol-2-yl-idene ring, with a dihedral angle of 85.5 (3)°. No hydrogen bonding is observed in the crystal.

Crystal structure of di-?-iodido-bis{[bis(piperidin-1-yl)methane-?(2) N,N']copper(I)}.

Project description:The title compound, [Cu2I2(C11H22N2)2], crystallizes as a symmetric dimer with one quarter of the mol-ecule in the asymmetric unit. The copper(I) atom, the iodine atom and the central methyl-ene C atom of the di(piperidin-1-yl)methane ligand lie on a mirror plane and the complete molecule exhibits point group symmetry 2/m. To the best of our knowledge it is the first di-amine copper(I) complex containing a four-membered chelate ring. Compared to other di-amine copper(I) iodide dimers, the title compound has a short Cu?Cu distance of 2.5137?(11)?Å, but a long Cu-N bond length of 2.213?(3)?Å. The I-Cu-I angle [121.84?(2)°] is large, and the N-Cu-N angle = 66.61?(13)° is the smallest one found for copper(I) di-amine complexes. As a result of the four-membered ring, the ligands around the copper(I) atom have an extremely distorted tetra-hedral arrangement. In the crystal, there are no significant inter-molecular inter-actions present.

Triphen-yl(pyrrolidine-1-carbodi-thio-ato-?S)tin(IV).

Project description:In the title compound, [Sn(C6H5)3(C5H8NS2)], the Sn(IV) atom adopts a distorted SnC3S tetra-hedral coordination geometry [spread of bond angles = 94.43?(7)-120.74?(7)°]. A short intra-molecular Sn?S contact [3.0270?(9)?Å] occurs and two intra-molecular C-H?S inter-actions help to establish the conformation. Three of the methyl-ene groups of the pyrrolidine-1-carbodi-thio-ate ligand are disordered over two sets of sites of equal occupancy. In the crystal, very weak C-H?S inter-actions link the mol-ecules into a three-dimensional network, with both S atoms acting as acceptors.

catena-Poly[[bis-(?(2)-1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne)dipotassium]-?(2)-iodido-(iodidocadmium)-di-?(2)-iodido-(iodidocadmium)-?(2)-iodido].

Project description:The reaction of CdCl(2), 18-crown-6 and KI in water yields the title coordination polymer, [{K(C(12)H(24)O(6))}(2)Cd(2)I(6)](n). The potassium ion lies approximately in the plane of the crown ether, coordinated by all six crown ether O atoms and also by an iodide anion bound to a cadmium atom. A C atom of the crown ether is disordered over two positions with site occupancies of 0.77?(2) and 0.23?(2). Two K(18-crown-6)(+) units are linked by inversion symmetry, forming a [bis-(?(2)-18-crown-6)dipottasium] system with approximately square-planar K(2)O(2) units. Inversion symmetry also generates the Cd(2)I(6) fragment and the polymeric system is extended along the c axis by the formation of K-I-Cd bridges.

Dipotassium hexa-aqua-nickel(II) bis-[hexa-fluoridozirconate(IV)].

Project description:Single crystals of the title compound, K(2)[Ni(H(2)O)(6)][ZrF(6)](2), were grown by slow evaporation of a 40% aqueous HF solution in which a stoichiometric mixture of NiCl(2)·6H(2)O, ZrF(4) and KCl was dissolved. The monoclinic structure is isotypic with its K(2)Cu, K(2)Zn, Cs(2)Zn and Cs(2)Cu analogues. The structure is built up from isolated, slightly elongated octa-hedral [Ni(H(2)O)(6)](2+) complex cations (symmetry ) and dimeric [Zr(2)F(12)](4-) complex anions (symmetry ) that are also isolated from each other. The [Zr(2)F(12)](4-) anion results from the association of two distorted penta-gonal-bipyramidal [ZrF(7)] coordination polyhedra by sharing an equatorial edge passing through an inversion center of the unit cell. Both isolated [Ni(H(2)O)(6)](2+) and [Zr(2)F(12)](4-) complex ions are situated in planes parallel to (010). They are connected by the eight-coordinated K(+) ions into a three-dimensional structure. An intricate O-H?F hydrogen-bonding network consolidates the structure.

Crystal structure of hepta-guanidinium nona-hydrogen bis-[α-hexa-molybdoplatinate(IV)] hepta-hydrate.

Project description:The title compound, (CH6N3)7H9[PtMo6O24]2·7H2O, containing the well-known Anderson-type heteropolyoxomolybdate, was obtained by recrystallization of its powdered guanidinium salt. The protonated O atoms in the polyanion were confirmed by electron-density maps, inter-polyanion hydrogen bonds and bond-valance sums (BVS). The {[H4.5PtMo6O24]2}(7-) polyanion is the same as that already characterized in K7[H4.5PtMo6O24]2·11H2O [space group P-1; Lee & Joo (2010 ▶). Acta Cryst. E66, i8-i9]. The heteropolyanions form inversion-generated dimers, {[H4.5PtMo6O24]2}(7-), held together by each of the four μ3-O-H⋯μ1-O, two μ2-O-H⋯μ2-O hydrogen bonds and one centrosymmetric μ3-O-H-μ3-O hydrogen bond. The H atom of the centrosymmetric hydrogen bond is located on an inversion centre. One guanidinium ion and one water mol-ecule are equally disordered about a twofold rotation axis.
