Catena-Poly[copper(II)-di-?-dicyan-amido-?-1,3-di-4-pyridylpropane].

ABSTRACT: In the title compound, [Cu(C(2)N(3))(2)(C(13)H(14)N(2))](n), the Cu(II) atom, located on an inversion centre, adopts a distorted octa-hedral coordination by six N atoms, two from 1,3-di-4-pyridylpropane and four from dicyanamide ligands, with significantly different Cu-N distances. The metal centres are linked in an unusual triple-bridged mode into chains parallel to [101].

Project description:In the title compound, [CoCl(2)(C(13)H(14)N(2))](n), 1,3-bis-(4-pyrid-yl)propane (bpp) ligands bridge four-coordinate Co atoms, generating an extended one-dimensional zigzag chain. Both the Co and two Cl atoms in the tetrahedral coordination polyhedron lie on a mirror plane, while the bbp ligand is bis-ected through the central C atom in the chain by a second mirror plane. There are some π-π stacking inter-ations in the crystal structure, with inter-planar distances of 3.449 Å, which are responsible for the supra-molecular assembly.

Project description:In the title compound, [Cd(C(7)H(7)S)(2)(C(13)H(14)N(2))](n), the unique Cd(II) ion, located on a twofold rotation axis, is coordinated by two S atoms and two N atoms in a slightly distorted tetra-hedral environment. Symmetry-related Cd(II) ions are linked via bridging 1,3-di-4-pyridylpropane ligands, forming a zig-zag chain-structure parallel to [001]. In the crystal structure, there are weak intra-chain π-π stacking inter-actions between benzene rings, with a centroid-centroid distance of 3.825 (7) Å, and pairs of chains are inter-digitated with respect to the 4-methyl-benzene-thiol-ate groups.

Project description:In the title compound, [Pd(C(7)H(7)O(3)S)(2)(C(13)H(14)N(2))(2)](n), the metal ion, located on a twofold rotation axis, exhibits a slightly distorted octa-hedral coordination environment, with bond angles that deviate by at most 2.2° from an ideal geometry, completed by two O atoms from two deprotonated p-toluene-sulfonic acid ligands and four N atoms from four 1,3-di-4-pyridylpropane ligands.

Project description:In the title compound, [Cu(C(8)H(4)NO(6))(2)(C(13)H(14)N(2))](n), the square-planar coordinated Cu(II) ion lies on an inversion centre and is coordinated by two protonated 5-nitro-isophthalate ligands. The Cu(II) ions are linked into a one-dimensional coordination polymer by tethering 1,3-di-4-pyridylpropane ligands, whose central methyl-ene C atoms are situated on twofold rotation axes. The chains are oriented parallel to the c axis, and stack into a supra-molecular three-dimensional structure through O-H?O hydrogen-bonding inter-actions.

Project description:In the title compound, {[Co(C(7)H(3)NO(5))(C(13)H(14)N(2))(H(2)O)]·2H(2)O}(n), the Co(II) atom is coordinated by two O atoms from a pyridine-2,6-dicarboxyl-ate N-oxide ligand, two N atoms from two 1,3-di-4-pyridylpropane ligands and one water mol-ecule, and displays a distorted square-pyramidal coordination geometry. The 1,3-di-4-pyridylpropane ligands link the Co(II) atoms into an infinite zigzag chain parallel to [010]. The chains are further linked through O-H?O and C-H?O hydrogen bonds, forming a three-dimensional supra-molecular network.

The asymmetric unit also contains one uncoordinated 1,3-di-4-pyridylpropane mol-ecule, one 2-methyl-4-nitro-aniline mol-ecule and one perchlorate anion. In the crystal structure, inter-molecular O-H?N hydrogen bonds connect the one-dimensional chains into a two-dimensional network.

Crystal structure of catena-poly[1,3-di-benzyl-benzimidazolium [[chlorido-mercurate(II)]-di-?-chlorido]].

Project description:The asymmetric unit of the polymeric title compound, {(C21H19N2)[HgCl3]} n , comprises one-half of the cationic mol-ecule, the other half being generated by application of twofold rotation symmetry, one Hg and two Cl atoms. The Hg(II) atom, lying on a twofold rotation axis, exhibits a distorted triangular coordination environment and is surrounded by three Cl atoms with Hg-Cl distances in the range 2.359?(2)-2.4754?(13)?Å. Two additional longer distances [Hg?Cl = 3.104?(14)?Å] lead to the formation of polymeric [HgCl1/1Cl4/2](-) chains extending along [001]. The crystal packing can be described by cationic layers alternating parallel to (-110) with the anionic chains located between the layers. The packing is consolidated by ?-? stacking inter-actions between the benzene rings of the central benzimidazole entities, with centroid-to-centroid distances of 3.643?(3)?Å.
