Crystal structure of non-centrosymmetric bis-(4-meth-oxy-benzyl-ammonium) tetra-chlorido-zincate.

ABSTRACT: The structure of the title non-centrosymmetric organic-inorganic hybrid salt, (C8H12NO)2[ZnCl4], consists of two 4-meth-oxy-benzyl-ammonium cations sandwiched between anionic layers, formed by isolated tetra-chlorido-zincate tetra-hedra. The double layers extend parallel to the ac plane. The crystal packing is assured by Coulombic inter-actions and by a complex N-H⋯Cl and C-H⋯Cl hydrogen-bonding system mostly involving the positively charged ammonium groups and the chloride ligands of the isolated tetra-hedral [ZnCl4](2-) units. One of the methyl-ene-ammonium groups is disordered over two sets of sites in a 0.48 (2):0.52 (2) ratio. The crystal investigated was twinned by non-merohedry with a twin component ratio of 0.738 (2):0.262 (2).

Project description:Phase VI of bis-(tetra-methyl-ammonium) tetra-chloro-zincate(II), (C(4)H(12)N)(2)[ZnCl(4)], contains three formula units per asymmetric unit. Several short C-H⋯Cl contacts [2.70 (3) and 2.72 (4) Å] are observed, but they are believed to participate only in van der Waals inter-actions. The crystal studied exhibited inversion twinning.

Bis(4-meth-oxy-benzyl-ammonium) dihydrogen diphosphate.

Project description:In the title compound, 2C(8)H(12)NO(+)·H(2)P(2)O(7) (2-), the linked PO(4) groups of the diphosphate anion are almost eclipsed and the P-O-P angle is 134.45?(7)°.

The 4-meth-oxy-benzyl-ammonium cations bond to the diphosphate chains by N-H?O and C-H?O links, and are themselves linked by C-H?? inter-actions.

Bis(1,10-phenanthrolin-1-ium) tetra-chlorido-zincate monohydrate.

Project description:In the crystal structure of the title compound, (C12H9N2)2[ZnCl4]·H2O, the two independent 1,10-phenanthrolinium cations are bridged by the water mol-ecule and the tetrahedral tetrachloridozincate anion via N-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds, forming chains along [100]. The chains are linked via C-H⋯Cl hydrogen bonds and a number of π-π inter-actions [centroid-centroid distances vary from 3.5594 (14) to 3.7057 (13) Å], forming a three-dimensional network. In each 1,10-phenanthrolinium cation, there is a short N-H⋯N inter-action.

Bis(triethyl-ammonium) tetra-chlorido-cobaltate(II).

Project description:The crystal structure of the title compound, (C(6)H(16)N)(2)[CoCl(4)], is comprised of a tetrahedral [CoCl(4)](2-) anion and two independent triethyl-ammonium cations. The latter are featureless while the [CoCl(4)](2-) anion exhibits typical Co-Cl bond lengths [2.2428?(15)-2.2847?(16)?Å] and a Cl-Co-Cl angular range of 107.58?(6)-112.73?(7)°. In the crystal, N-H?Cl hydrogen bonds between the two crystallographically independent cations and the [CoCl(4)](2-) anion generate discrete ion triplets. The two Co-Cl bonds involved in these inter-actions are slightly longer than the remaining two.

Crystal structure of bis-[trans-(1,4,8,11-tetra-aza-cyclo-tetra-decane-?(4) N)bis-(thio-cyanato-?N)chromium(III)] tetra-chlorido-zincate from synchrotron data.

Project description:The structure of the title compound, [Cr(NCS)2(cyclam)]2[ZnCl4] (cyclam = 1,4,8,11-tetra-aza-cyclo-tetra-decane, C10H24N4), has been determined from synchrotron data. The asymmetric unit contains two independent halves of the Cr(III) complex cations and half of a tetra-chlorido-zincate anion. In each complex cation, the Cr(III) atom is coordinated by the four N atoms of the cyclam ligand in the equatorial plane and by two N-bound NCS(-) anions in a trans axial arrangement, displaying a distorted octa-hedral geometry with crystallographic inversion symmetry. The mean Cr-N(cyclam) and Cr-N(NCS) bond lengths are 2.065?(4) and 1.995?(6)?Å, respectively. The macrocyclic cyclam moieties adopt centrosymmetric trans-III configurations with six- and five-membered chelate rings in chair and gauche configurations, respectively. The [ZnCl4](2-) anion, which lies about a twofold rotation axis, has a slightly distorted tetra-hedral geometry. The crystal packing is stabilized by hydrogen-bonding inter-actions between the N-H groups of the cyclam ligands, the S atoms of the NCS(-) groups and the Cl(-) ligands of the anion.

Crystal structure of the thermochromic bis-(di-ethyl-ammonium) tetra-chlorido-cuprate(II) complex.

Project description:In the structure of the title complex salt, (Et2NH2)2[CuCl4], the asymmetric unit consists of four unique di-ethyl-ammonium cations and three unique tetra-chlorido-cuprate anions. Two of the three anions are located with their copper atoms on independent crystallographic twofold axes, while the remaining tetra-chlorido-cuprate is located at a general position of the ortho-rhom-bic space group P21212. Two of the three Cu atoms adopt a distorted square-planar/disphenoidal geometry and the third Cu atom has a regular square-planar coordination environment. The di-ethyl-ammonium cations form an extensive hydrogen-bonded network through N-H⋯Cl inter-actions with the tetra-chlorido-cuprate anions, resulting in a two-dimensional sheet-like hydrogen-bonded network parallel to the ab direction. The complex was observed to undergo a color shift from deep green at room temperature to pale yellow at temperatures above 328 K.
