Eight mixed-ligand coordination networks, [Cd(2-aba)(NO)(4-bphz)]·n(dmf) (), [Cd(2-aba)(4-bphz)]·0.75n(dmf) (), [Cd(seb)(4-bphz)]·n(HO) (), [Cd(seb)(4-bpmhz)]·n(HO) (), [Cd(hpa)(3-bphz)] (), [Zn(1,3-bdc)(3-bpmhz)]·n(MeOH) (), [Cd(1,3-bdc)(3-bpmhz)] ·0.5n(HO)·0.

A one-dimensional coordination polymer based on Cu3-oximato metallacrowns bridged by benzene-1,4-dicarboxylato ligands: structure and magnetic properties.

A one-dimensional linear coordination polymer {[Cu3(μ3-OH)(2-pyao)3(bdc)]·6(H2O)}n () composed of trinuclear [Cu3(μ3-OH)(2-pyao)3](2+) metallacrown cores bridged by bis-carboxylato linkers has been obtained by treatment of copper(ii) fluoride with pyridine-2-aldoxime (2-pyaoH) ligand and benzene-1,4-dicarboxylic acid (H2bdc). Magnetic susceptibility measurements show strong antiferromagnetic interactions between Cu(ii) centers within the trinuclear metallacrown core with J = -430 cm(-1).

Two Zn(II) mononuclear coordination compounds with pyridinedicarboxylate and auxiliary N-(pyridin-4-ylmethylidene)hydroxylamine ligands.

Two new mononuclear coordination compounds, bis{4-[(hydroxyimino)methyl]pyridinium} diaquabis(pyridine-2,5-dicarboxylato-κ(2)N,O(2))zincate(II), (C6H7N2O)2[Zn(C7H3NO4)2(H2O)2], (1), and (pyridine-2,6-dicarboxylato-κ(3)O(2),N,O(6))bis[N-(pyridin-4-ylmethylidene-κN)hydroxylamine]zinc(II), [Zn(C7H3NO4)(C6H6N2O)2], (2), have been synthesized and characterized by single-crystal X-ray diffractometry. The centrosymmetric Zn(II) cation in (1) is octahedrally coordinated by two chelating pyridine-2,5-dicarboxylate ligands and by two water molecules in a distorted octahedral geometry. In (2), the Zn(II) cation is coordinated by a tridentate pyridine-2,6-dicarboxylate dianion and by two N-(pyridin-4-ylmethylidene)hydroxylamine molecules in a distorted C2-symmetric trigonal bipyramidal coordination geometry.

Di-aqua-bis-(pyridine-2-carboxyl-ato-κ(2) N,O)zinc di-methyl-formamide hemisolvate.

In the title compound, [Zn(C6H4NO2)2(H2O)2]·0.5C3H7NO, the Zn(II) ion is coordinated in a distorted octa-hedral N2O4 environment by two N,O-chelating pyridine-2-carboxyl-ate ligands and two cis water mol-ecules. The chelating pyridine-2-carboxyl-ate ligands create two five-membered Zn/N/C/C/O rings, which form a dihedral angle of 86.

Bis[2-(hy-droxy-imino)-cyclo-hexan-1-one oximato-κ(2) N,N']copper(II).

In the title compound, [Cu(C6H9N2O2)2], the Cu(II) atom is located on an inversion center and has a square-planar environment. Two 2-(hy-droxy-imino)-cyclo-hexan-1-one oxim-ate monoanions chelate to the Cu(II) atom and the Cu-N distances are 1.920 (3) and 1.
