Popis:	The Cu atom in the title complex, [Cu(C25H20N3O2)2(H2O)], has a distorted trigonal-bipyramidal coordination environment, with two O atoms of the pyrazolone rings and a water O atom in the equatorial plane and two N atoms in axial positions [N—Cu—N = 159.34 (16)°]. The complex occupies a special position on a twofold axis running through the Cu atom and the water O atom. The Cu—O(H2O) bond [2.549 (4) A] is substantially longer than the rest of the bonds in the coordination polyhedron [Cu—O = 1.919 (2) A and Cu—N = 1.990 (3) A]. The pyrazolone ring is almost coplanar with the adjacent chelate ring, the dihedral angle formed by the mean plane of the pyrazolone ring and the planar part of the chelate ring being 2.91 (3)°.
