Catena-Poly[[dichloridoiron(II)]-?-4,4''-bis-(benzimidazol-1-yl)-1,1':4',1''-terphen-yl].

ABSTRACT: In the title coordination polymer, [FeCl(2)(C(32)H(22)N(4))](n), the Fe(II) atom lies on a crystallographic twofold axis and a distorted FeCl(2)N(2) tetra-hedral coordination geometry arises. The complete ligand is generated by crystallographic twofold symmetry, resulting in an infinite one-dimensional architecture along [101].

Project description:In the title one-dimensional coordination polymer, [Cu(NO(3))(2)(C(32)H(22)N(4))](n), the Cu(2+) ion (site symmetry 2) is coordinated by two nitrate O atoms and two N atoms from two 4,4'-bis-(benzoimidazol-1-yl)terphenyl (L) ligands in a distorted cis-CuN(2)O(2) square-planar coordination geometry. An alternative description of the metal coordination geometry, if long Cu-O contacts to the bonded nitrate anions are considered, is an extremely distorted cis-CuN(2)O(4) octa-hedron. The complete L ligand is generated by crystallographic twofold symmetry and connects the metal ions into infinite chains propagating in [10[Formula: see text]]. The dihedral angle between the benzimidazole ring system and the adjacent benzene (B) ring is 51.12?(11)° and the dihedral angle between the B ring and the central ring is 19.45?(13)°.

Project description:The title compound, {(C(14)H(18)N(2))[Pb(2)I(6)]}(n), consists of discrete 1,1'-dimethyl-4,4'-(ethane-1,2-di-yl)dipyridinium cations and one-dimensional [Pb(2)I(6)](n) anions.

Project description:In the title compound, {[Cu(C(7)H(6)NO(2))(2)(C(11)H(16)N(4))]·3H(2)O}(n), each Cu(II) atom is coordinated by two O atoms from two 4-amino-benzoate anions, and two N atoms from two different 1,1'-(pentane-1,5-di-yl)diimidazole (biim-5) ligands, to furnish a distorted square-planar geometry.

The polymeric chains are linked through a variety of hydrogen bonds to form a three-dimensional structure.
