Employment of N,N′-bis(2-dicarboxyphenyl)-oxalamide (H4L) in the M2+ chemistry (M = Mg, Mn, Co, Ni, and Zn) afforded five 2-D coordination polymers and one 1-D coordination polymer. The crystal structures of all complexes have been determined by single-crystal X-ray crystallography. The five 2-D polymers with the general formula [M(H2L)(H2O)2] n (M = Mg 1, Mn 2, Co 3, Ni 4, Zn 6) are based on the di-anion of the oxalamide ligand (H2L2–) while the poorly diffracting complex 5, {[Ni2(L)(H2O)3]·(H2O)2} n, is based on the tetra-anion of the oxalamide ligand (L4–). The magnetic properties of 2–4 revealed weak antiferromagnetic interactions between the spin carriers. © 2020 Informa UK Limited, trading as Taylor & Francis Group.
