文摘

Two novel heterobimetallic three-dimensional coordination polymers, [Cu₂Na₄L₂(CH₃OH)_2.3(H₂O)_5.2]路1.7H₂O (1) and [CuNa₂L(H₂O)_3.88]路H₂O (2), have been obtained by assembling a bis-oxamate copper(II) complex with sodium ions (L = 4,4鈥?sulfonylbis(phenylene)bis(oxamate). Both coordination frameworks are constructed by connecting {Cu₄L₄} crosslike anionic units by sodium ions forming polymers with different topologies. The magnetic susceptibility data shows weak antiferromagnetic interaction for both compounds.
