چکیده
The title compound, {[Cu2(C7H4O3)2(H2O)2]·2H2O} n , contains two copper(II) cations in special positions (one on a twofold rotation axis and one on an inversion centre) and the the salicylate ligand in its dianionic form. By four- and six-coordinate metal coordination, chains are formed parallel to [001], which are extended by O-H⋯O hydrogen bonding into sheets extending parallel to (100). These sheets are weakly connected by O-H⋯O hydrogen bonding via the non-coordinating lattice water mol-ecules into a three-dimensional network.

In the title complex, {[Cu3[W(CN)8]2(C5H6N2)4(H2O)2]·2H2O} n , the coordination polyhedron of the eight-coordinated W(V) atom is a bicapped trigonal prism, in which five CN groups are bridged to Cu(II) ions, and the other three CN groups are terminally bound. Two of the Cu(II) ions lie on a centre of inversion and each of the three independent Cu(II) cations is pseudo-octahedrally coordinated. ...

The title polymeric compound, [Cu2(C8H7O2)4] n , was synthesized by the reaction of copper acetate with aqueous phenyl-acetic acid. The unique Cu(II) atom is coordinated by five O atoms from the carboxyl-ate groups of phenyl-acetate ligands, and the strongly distorted octa-hedral coordination environment is completed by a Cu-Cu bond of 2.581 (2) Å, at whose mid-point is located an inversion cen...

In the title complex, {[Cu(SiF(6))(C(11)H(8)N(2)O)(2)]·2H(2)O}(n), the Cu(II) atom adopts an N(4)F(2)-octa-hedral coordination geometry with four pyridine N atoms in the equatorial sites and two F atoms in the axial sites. The di-3-pyridyl-methanone and hexa-fluoro-silicate ligands act as bidentate ligands, linking symmetry-related Cu(II) atoms. Water mol-ecules form O-H⋯O and O-H⋯F hydrogen bo...

The structure of the title compound, [Cd(3)Cl(6)(C(15)H(15)NO(2))(2)(CH(4)O)(2)](n), is based on a layered zigzag polymeric chain along the c axis. The Cd(II) ions are linked by double chlorine bridges alternating between one CdCl(4)(CH(3)OH)(2) and two CdCl(4)(C(15)H(15)NO(2)) octa-hedral coordination units. Additional intrachain N-H⋯O and O-H⋯Cl hydrogen-bond interactions stabilize this arran...

The title compound, {[Cu(C(20)H(14)N(4))(2)][Cu(2)(NCS)(4)]}(n), was obtained by reacting copper acetate hydrate, ammonium thio-cyanate and 4'-(3-pyrid-yl)-2,2':6',2''-terpyridine (3-pytpy) under solvothermal conditions. The polymeric complex is isostructural with the 4'-phenyl-2,2':6',2''-terpyridine (phtpy) analogue. All intramolecular distances and angles are very similar for the two structu...
