Catena-Poly[(dichloridozinc)-?-bis-(pyridin-3-yl)methanone-?N:N'].

ABSTRACT: In the title polymer, [ZnCl(2)(C(11)H(8)N(2)O)](n), the Zn(II) atom lies on a twofold rotation axis and has a distorted tetra-hedral ZnCl(2)N(2) geometry involving two chloride donors and two N-atom donors from ?(2)-bridging bis-(pyridin-3-yl)methanone ligands, which also have twofold symmetry. A zigzag chain structure is formed, extending along (001). Each chain is surrounded by three others which are inter-connected through weak C=O??(pyrid-yl) [O?centroid = 2.999?(3)?Å] and ?(pyrid-yl)-?(pyrid-yl) inter-actions [minimum ring centroid separation = 4.014?(2)?Å], giving a three-dimensional framework.

Project description:In the title complex, {[Cd(CH(3)COO)(2)(C(11)H(8)N(2)O)(H(2)O)]·2H(2)O}(n), the Cd(II) ion adopts an O(5)N(2) penta-gonal-bipyramidal coordination geometry with four acetate O atoms and one water O atom at the equatorial sites and two pyridine N atoms at the axial sites. The (pyridin-3-yl)(pyridin-4-yl)methanone ligand acts in a ?(2)-bridging mode, linking the metal atoms, leading to an infinite chain along [-110]. O-H?O hydrogen bonds involving the lattice water mol-ecules connect these chains into a three-dimensional network.

Project description:In the title compound, [ZnCl(2)(C(18)H(16)N(2)O(2))](n), the Zn(II) ion is tetra-hedrally coordinated by two Cl atoms and by two N atoms from different 1,4-bis-(pyridin-2-ylmeth-oxy)benzene ligands. The ligand shows a non-planar configuration, in which the dihedral angles between the two terminal pyridine rings and the linking benzene ring are 7.86?(12) and 70.74?(11)°. The flexible ligand coordinates to the Zn(II) ions, generating an infinite chain propagating along [001].

catena-Poly[[dichloridozinc(II)]-μ-1,4-bis-(3-pyridylmeth-yl)piperazine].

Project description:In the title compound, [ZnCl(2)(C(16)H(20)N(4))](n), tetra-hedrally coordinated divalent Zn atoms are ligated by two Cl atoms and two N-donor atoms from two 1,4-bis-(3-pyridylmeth-yl)-piperazine (3-bpmp) ligands. The tethering 3-bpmp ligands promote the formation of [ZnCl(2)(3-bpmp)](n) chains situated parallel to (02). These chains aggregate via C-H⋯Cl inter-actions to form supra-molecular layers, which in turn stack to construct the three-dimensional crystal structure.

catena-Poly[[[di-aqua-bis-[1,2-bis-(pyridin-4-yl)diazene]copper(II)]-μ-1,2-bis-(pyridin-4-yl)diazene] bis-(perchlorate)].

Project description:In the title compound, {[Cu(C10H8N4)3(H2O)2](ClO4)2} n , the coordination environment of the cationic Cu(II) atom is distorted octa-hedral, formed by pairs of symmetry-equivalent 1,2-bis-(pyridin-4-yl)diazene ligands, bridging 1,2-bis-(pyridin-4-yl)diazene ligands and two non-equivalent water mol-ecules. The 1,2-bis-(pyridin-4-yl)diazene mol-ecules form polymeric chains parallel to [-101] via azo bonds which are situated about inversion centres. Since the Cu(II) atom is situated on a twofold rotation axis, the monomeric unit has point symmetry 2. The perchlorate anions are disordered in a 0.536 (9):0.464 (9) ratio and are acceptors of water H atoms in medium-strong O-H⋯O hydrogen bonds with graph set R 4 (4)(12). The water mol-ecules, which are coordinated to the Cu(II) atom and are hydrogen-bonded to the perchlorate anions, form columns parallel to [010]. A π-π inter-action [centroid-centroid distance = 3.913 (2) Å] occurs between pyridine rings, and weak C-H⋯O inter-actions also occur.
