Aqua-bis-(3,5-dimethyl-1H-pyrazole-κN)(oxydiacetato-κO,O',O'')copper(II) dihydrate

In the title compound, [Cu(C(4)H(4)O(5))(C(5)H(8)N(2))(2)(H(2)O)]·2H(2)O, the Cu(II) cation assumes a distorted octa-hedral coordination geometry formed by two 3,5-dimethyl-1H-pyrazole ligands, one oxydiacetate (ODA) dianion and one coordinated water mol-ecule. The tridentate ODA ligand chelates to the Cu cation in a facial configuration with a longer Cu-O bond [2.597 (3) Å], and both chelating rings display envelope conformations. In the mol-ecule, the two pyrazole rings are twisted with respect to each other at a dihedral angle of 57.5 (3)°. Extensive inter-molecular O-H⋯O and N-H⋯O hydrogen bonding is present in the crystal structure.
