Poly[1,4-bis-(ammonio-meth-yl)cyclo-hexane [di-?-chlorido-dichloridoplumbate(II)]].

ABSTRACT: The title compound, {(C(8)H(20)N(2))[PbCl(4)]}(n), crystallizes as an layered inorganic-organic hybrid perovskite-type structure. Corner-sharing PbCl(6) octa-hedra extend parallel to the ac plane. Adjacent layers are staggered relative to one another, with diammonium cations separating these layers. The cations exhibit symmetry and inter-act with the inorganic sheets via N-H?Cl hydrogen bonding in the right-angled halogen sub-type of the terminal halide hydrogen-bonding motif.

Poly[[?-1,4-bis-(imidazol-1-ylmeth-yl)benzene]bis-(?(4)-cyclo-hexane-1,4-dicarboxyl-ato)dinickel(II)].

Project description:The structure of the polymeric title compound, [Ni(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), features a five-coordinate Ni(II) centre defined by four carboxyl-ate O atoms from two different cyclo-hexane-1,4-dicarboxyl-ate (chdc) ligands and an N atom from one end of a 1,4-bis-(imidazol-1-ylmeth-yl)benzene (1,4-bix) mol-ecule. The NO(4) coordination geometry is distorted square-pyramidal with the N atom in the apical position. Each end of the chdc ligand links pairs of Ni(II) atoms into a paddle-wheel assembly, i.e. Ni(2)(O(2)CR')(4). These are connected into rows owing to the bridging nature of the chdc ligands, and the rows are connected into a two-dimensional grid via the 1,4-bix ligands. The 1,4-bix ligand, which is disposed about a centre of inversion, is disorderd. Two positions of equal occupancy were discerned for the -H(2)C(C(6)H(4))CH(2)- residue.

Poly[[?(2)-1,4-bis-(imidazol-1-ylmeth-yl)benzene]bis-(?(4)-cyclo-hexane-1,4-dicarboxyl-ato)dicobalt(II)].

Project description:In the title compound, [Co(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), the two Co(II) atoms are both five-coordinated by four carboxyl-ate O atoms, derived from two different cyclo-hexane-1,4-dicarboxyl-ate (chdc) ligands, and an N atom, derived from one end of a 1,4-bis-(imidazol-1-ylmeth-yl)benzene mol-ecule (1,4-bix), in a distorted square-pyramidal environment. Each end of the chdc ligand links pairs of Co(II) atoms into a paddle-wheel assembly, i.e. Co(2)(O(2)CR')(4); these are connected into rows because of the bridging nature of the chdc ligands, and the rows are further connected into a two-dimensional layer through the 1,4-bix ligands. The 1,4-bix ligand, which is disposed about a centre of inversion, is disorderd. Two positions were discerned for the -CH(2)(C(6)H(4))CH(2)- residue, with the major component having a site-occupancy factor of 0.512?(9).

2,2'-[(E,E)-cis-(Cyclo-hexane-1,4-di-yl)bis-(nitrilo-methanylyl-idene)]diphenol.

Project description:In the title compound, C(20)H(22)N(2)O(2), the asymmetric unit contains two independent half-mol-ecules, which are both completed by crystallographic inversion symmetry. The cyclo-hexane rings of both mol-ecules adopt chair conformations; the N atoms are in equatorial orientations in one mol-ecule and in axial orientations in the other. Both mol-ecules feature two intra-molecular O-H?N hydrogen bonds, which generate S(6) rings.

Poly[di-μ-cis-cyclo-hexane-1,4-dicarboxyl-ato-μ-trans-cyclo-hexane-1,4-dicarboxyl-ato-bis-[dipyrido[3,2-a:2',3'-c]phenazine]trimanganese(II)].

Project description:In the title compound, [Mn(3)(C(8)H(10)O(4))(3)(C(18)H(10)N(4))(2)], one Mn atom and one cyclohexane-1,4-dicarboxylate (chdc) ligand are located on centres of inversion. One of the two independent Mn atoms is seven-coordinate, binding to five carboxyl-ate O atoms from different chdc ligands and two phenanthrene N atoms from a dipyrido[3,2-a:2',3'-c]phenazine (L) ligand, while the second Mn atom is six-coordinate, binding to six carboxyl-ate O atoms from different chdc ligands. The cis-chdc ligands bridge the trinuclear Mn(II) clusters, forming chains, which are further linked into a three-dimensional network.

Crystal structure of diethyl 2,2'-[((1E,1'E)-{[(1R,4R)-cyclo-hexane-1,4-di-yl]bis-(aza-nylyl-idene)}bis-(methanylyl-idene))bis-(1H-pyrrole-2,1-di-yl)]di-acetate.

Project description:The whole mol-ecule of the title compound, C24H32N4O4, is generated by inversion symmetry. The cyclo-hexane ring adopts a chair conformation and the conformation about the C=N bonds is E. The pyrrole rings have an anti confirmation with respect to the cyclo-hexane moiety and the ethyl acetate groups have extended conformations. In the crystal, mol-ecules are linked by pairs of C-H⋯O hydrogen bonds forming chains, enclosing R 2 (2)(10) ring motifs with inversion symmetry, propagating parallel to the (101) plane.

Bis(1,4-diazo-niabi-cyclo-[2.2.2]octa-ne) di-μ-chlorido-bis-[tetra-chlorido-anti-monate(III)] dihydrate.

Project description:The title salt, (C6H14N2)2[Sb2Cl10]·2H2O, was obtained by slow evaporation of an acidic solution of 1,4-di-aza-bicyclo-[2.2.2]octane and SbCl3. The crystal structure consists of (C6H14N2)(2+) cations, [Sb2Cl10](4-) double octa-hedra and lattice water mol-ecules. All mol-ecular components are situated on special positions. The cation and the lattice water mol-ecule exhibit mirror symmetry, whereas the anion has site symmetry 2/m. The cations, anions and water mol-ecules are alternately arranged into columns along [010]. Individual columns are joined into layers extending along (001). Intra-layer N-H⋯O and inter-layer N-H⋯Cl hydrogen-bonding inter-actions lead to the formation of a three-dimensional network.

Poly[[[?-1,1'-(butane-1,4-di-yl)diimidazole-?N:N](?-cyclo-hexane-1,4-dicarboxyl-ato-?O,O:O,O)nickel(II)] 0.25-hydrate].

Project description:In the title coordination polymer, {[Ni(C(8)H(10)O(4))(C(10)H(14)N(4))]·0.25H(2)O}(n), the coordination of the Ni(II) ion is distorted octa-hedral. The 1,1'-(butane-1,4-di-yl)diimidazole ligand and the cyclo-hexane-1,4-dicarboxyl-ate dianion bridge metal centres, forming a two-dimensional (4,4) network. The network is consolidated by O-H?O hydrogen bonds between the statistically occupied water molecules and O atoms of the two carboxylate groups.

N,N'-Bis(di-phenyl-meth-yl)benzene-1,4-di-amine.

Project description:The complete mol-ecule of the title compound, C32H28N2, is generated by crystallographic inversion symmetry. The dihedral angles between the central aromatic ring and the pendant adjacent rings are 61.37 (16) and 74.20 (14)°. The N-H group does not participate in hydrogen bonds and there are no aromatic π-π stacking inter-actions in the crystal.
