catena-Poly[[dichloridocobalt(II)]-μ-1,3-di-4-pyridylpropane-κN:N'].

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.

catena-Poly[[bis-(2-hydr-oxy-2-phenyl-acetato-κO,O)zinc(II)]-μ-1,2-di-4-pyridylethane-κN:N'].

Project description:The title compound, [Zn(C(8)H(6)O(3))(2)(C(12)H(12)N(2))](n), consists of [Zn(Hopa)(2)] (H(2)opa = 2-hydr-oxy-2-phenyl-acetic acid or mandelic acid) units bridged by 1,2-di-4-pyridylethane (bpe) ligands, forming a polymeric chain developing parallel to the b axis. The bridging bpe ligand is arranged around a twofold axis passing through the middle of the ethane C-C bond. The geometry around the Zn(II) ion is distorted octa-hedral, constructed by four O atoms from two Hopa(-) ligands and two N atoms from two bridging bpe ligands. O-H⋯O hydrogen bonds link the chains, forming a three-dimensional network.

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. One of the sulfonate O atoms is disordered over two positions [ratio 0.70 (5):0.30 (5)].

Project description:In the title compound, [CoCl(2)(C(26)H(18)N(4))](n), the Co(II) atom (site symmetry 2) is tetra-hedrally coordinated by two chloride ions and two N atoms from 4,4'-bis-(benzimidazol-1-yl)biphenyl ligands: the complete ligand is generated by crystallographic twofold symmetry. The dihedral angle between the benzene rings is 34.67?(8)° and the angle between the benene ring and the adjacent benzimidazole ring system is 43.26?(10)°. The bridging ligand links the Co(II) atoms into chains propagating in [[Formula: see text]01].

Non-coordinating dipyridinium dications are present between the thiocyanatoferrate(II) chains and are connected to the anions via N-H⋯N and N-H⋯S hydrogen-bond interactions.
