Bis[3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinato-κO,N,N']copper(II) tetra-hydrate.

In the title complex, [Cu(C(11)H(9)ClN(3)O(2))(2)]·4H(2)O, the Cu(II) atom is in a distorted octa-hedral coordination environment, coordinated by four N atoms and two O atoms from two tridentate 3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands. The mol-ecules are linked via inter-molecular O-H⋯O hydrogen bonds involving water mol-ecules to form extended chains along [010], and there are short Cl⋯Cl contacts [3.153 (4) Å].
