Research output: Contribution to journalArticle


In the neutral title complex, [Cu(C3H2O4)(C5H8N2)(2-)(H2O)]. 2H(2)O or [Cu(mal)(dmp)(2)(H2O)]. 2H(2)O (mal is malonate and dmp is 3,5-dimethyl-1H-pyrazole), the Cu-II ion, in a slightly distorted square-pyramidal geometry, is coordinated by two O atoms of the bidentate malonate, the O atom of the water ligand and two N atoms from the two 3,5-dimethylpyrazole ligands. The mean Cu-N bond length is 2.007 (6) Angstrom, longer than the Cu-O-mal bonds [1.950 (5) Angstrom]. The apical position is occupied by a relatively strongly coordinated water molecule [Cu-O-water 2.288 (5) Angstrom]. The crystal structure is characterized by the layer motif of a hydrogen-bonded network.
