Catena-Poly[(dichloridozinc)-?-4,4'-bis-[(1H-imidazol-1-yl)meth-yl]biphenyl-?(2)N(3):N(3')].

ABSTRACT: In the title compound, [ZnCl(2)(C(20)H(18)N(4))](n), the Zn(II) ion lies on a twofold rotation axis and is four-coordinated in a tetra-hedral geometry defined by two Cl anions and two N atoms from two 4,4'-bis-[(imidazol-1-yl)meth-yl]biphenyl ligands. The mid-point of the ligand is located on an inversion center, and shows a trans conformation. The ligands link the Zn(II) ions, forming a chain structure along [10-1].

Project description:The asymmetric unit of the title compound, [ZnCl(2)(C(14)H(14)N(4))](n), contains a Zn(II) ion situated on a twofold rotation axis and one-half of a 1-{4-[(1H-imidazol-1-yl)meth-yl]benz-yl}-1H-imidazole (L) ligand with the benzene ring situated on an inversion center. The Zn(II) ion is coordinated by two chloride anions and two N atoms from two L ligands in a distorted tetra-hedral geometry.

Project description:In the crystal structure of the title coordination polymer/co-crystal, {[ZnCl(2)(C(18)H(18)N(4))]·C(18)H(18)N(4)}(n), the tetrahedrally coordinated Zn(II) ions are linked by the N-heterocycle into a linear chain.

Project description:In the polymeric title complex, [CdCl(2)(C(12)H(13)N(5))](n), the Cd(II) atom is five-coordinated by two N atoms from two bridging 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands, two bridging Cl atoms and one terminal Cl atom in a distorted trigonal-bipyramidal geometry. The Cd(II) atoms are connected alternately by the Cl atoms and bmei ligands, leading to a zigzag chain extending parallel to [011]. π-π inter-actions, with a centroid-centroid distance of 3.3016 (3) Å, help to stabilize the crystal packing.

catena-Poly[[[bis-(thio-cyanato-?N)zinc(II)]-?-1,2-bis-{[2-(2-pyrid-yl)-1H-imidazol-1-yl]meth-yl}benzene] 0.28-hydrate].

Project description:The title one-dimensional coordination polymer, {[Zn(NCS)(2)(C(24)H(20)N(6))(2)]·0.28H(2)O}(n), was obtained by the reaction of Zn(OAc)(2)·2H(2)O, KSCN and 1,2-bis-{[2-(2-pyrid-yl)-1H-imid-azol-1-yl]meth-yl}benzene (hereafter L). The Zn(II) ion shows a distorted octa-hedral coordination geometry and is coordin-ated by two N atoms from two SCN(-) anions and four N atoms from two organic ligands. The L ligands act as bridging bis-chelating ligands with cis coordination modes at the Zn(II) ion. One-dimensional coordination polymers are arranged into layers by ?-? stacking inter-actions between the imidazole rings of adjacent chains, with an inter-planar distance of 3.46?(1)?Å and centroid-centroid distances of 3.8775?(16)?Å. One of the thio-cyanate ligands is disordered over two positions with an occupancy factor of 0.564?(3) for the major component. The partially occupied water mol-ecule forms an O-H?S hydrogen bond with the disordered thio-cyanate group.

catena-Poly[[bis-(nitrato-?O,O')cobalt(II)]-?-4,4'-bis-(pyrazol-1-ylmeth-yl)biphenyl-?N:N].

Project description:In the title compound, [Co(NO(3))(2)(C(20)H(18)N(4))](n), the Co(II) atom lies on a crystallographic twofold axis and the coordination geometry can be considered as a slightly distorted tetra-hedron defined by two O atoms from two nitrate groups and two N atoms from two ligand mol-ecules. A distorted octa-hedron may be assumed when two of the symmetry-related nitrate O atoms with Co-O distances of 2.3449?(19)?Å are added to the coordination environment. Another twofold axis, passing through the middle of the biphenyl bonds, is observed in the crystal structure. A chain is built up by the ligands linking the Co(II) ions along [101].
