Dimeric (pyrazole-N2)(N-salicylidene-2,2-dimethylglycinato-O,N,O′)copper(II) pyrazole solvate

In the title compound, bis(mu-N-salicylidene-2,2-dimethylglycinato)bis [(pyrazole)copper(II)] bis(pyrazole) solvate, [Cu-2(C11H11NO3)(2)(C3H4N2)(2)]. 2C(3)H(4)N(2), the Cu-II atom adopts a square-pyramidal copper(II) coordination with both a tridentate 2,2-dimethyl-N-salicylideneglycinate Schiff base dianion and a pyrazole ligand forming the basal plane. The apex of the pyramid is occupied by an O atom from an adjacent chelate molecule at a distance of 2.605 (2) Angstrom, building a centrosymmetric dimer. All copper polyhedra belonging to one dimer are oriented parallel to each other, whereas the dimers are ordered antiferrodistortively.
