Two novel heterobimetallic three-dimensional coordination polymers, [Cu2Na4L2(CH3OH)2.3(H2O)5.2]·1.7H2O (1) and [CuNa2L(H2O)3.88]·H2O (2), have been obtained by assembling a bis-oxamate copper(II) complex with sodium ions (L = 4,4′-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.
