Synthesis, X-ray structures, and magnetic properties of seven polynuclear Cu(ii) complexes containing pyrazole-3,5-dicarboxylate with various ancillary ligands

A series of polynuclear Cu( ii ) complexes were successfully synthesized under the reaction of Cu(NO 3 ) 2 ·3H 2 O, pyrazole-3,5-dicarboxylic acid, and various ancillary ligands and the structure-magnetic relationship of complexes was investigated.
