A 1-D copper(II) coordination polymer formulated as {[Cu2(bdpox)(dabt)](NO3)?H2O}n, where H3bdpox and dabt denote N-benzoate-N'-[3-(diethylamino)propyl]oxamide and 2,2'-diamino-4,4'-bithiazole, respec

, p. 64 - 65 (2008)
Two novel coordination polymers (CPs), {Cu[Cu(L)(H2O)-(py)] 2}n (1) and {Cu[Cu(L)(MeOH)]2·2H 2O}n (2), were synthesized using 2-(oxaloamino)benzoic acid (H3L) providing oxamate and carboxylate groups, and magnetically characterized. Different 2-D layer structures were formed based on oxamato-bridged tricopper units bridging via the carboxylate group. In compound 1, a simple antiferromagnetic interaction operates through the oxamato bridge in the tricopper core, whereas, 2 showed a tendency for ferrimagnetic ordering at 2 K, resulting from mixed antiferromagnetic and ferromagnetic interactions through oxamato and syn-anti-type carboxylato bridges.

experimental part, p. 1240 - 1244 (2011/01/08)
A new dissymmetrical oxamidate ligand has been used to construct a metal-organic network. Using this ligand, a novel coordination polymer, namely {[Cu(obea)]2Cu.CH3OH.H2O}n (1) [H3obea = N1-(2-carboxyphenyl)-N2-(2-hydroxyethyl)oxalamide] has been synthesized and characterized by single-crystal X-ray analysis. The structure of complex 1 consists of neutral trinuclear complex units. Through syn-anti carboxylate bridges, the complex features a 2D structure with a helical substructure. Its magnetic properties have been investigated.
