Molecular and crystal structures of a new complex compound of copper(II) with 3-methyl-5-carboxylatopyrazole (CH3PzCOO-) with the composition Cu(CH3PzCOO)2•H2O have been determined by single crystal XRD. It has been demonstrated that the carboxylate ion performs the bridging tridentate function. In the equatorial plane coordination occurs through the pyridine N atom of the pyrazole and one of O atoms of the carboxylate group yielding a five-membered metallocycle CuNOC 2. The second O atom of one of the ligands is bound to the neighboring copper(II) ion affording an infinite linear chain. The coordination polyhedron of the copper atom is a square pyramid, coordination core CuN 2O3.
