Synthesis, structure and magnetic studies of two-dimensional network of Cu(II) polymer using malonate and 4,4′-azobispyridine ligands

Synthesis, structure and magnetic studies of two-dimensional network of Cu(II) polymer using malonate and 4,4′-azobispyridine ligands The malonato-bridged copper(II) complex [Cu(mal)(H2O)(azpy)1/2] · H2O (1) has been synthesized and structurally characterized. The ferromagnetic coupling of intrachain [Cu(mal)]n and interchain antiferromagnetic coupling were observed.
