Crystal structure of di­chlorido-1κCl,2κCl-(μ(2)-3,5-dimethyl-1H-pyrazolato-1κN (2):2κN (1))(3,5-dimethyl-1H-pyrazole-2κN (2)){μ-2-[(2-hy­droxy­eth­yl)amino-1κ(2) N,O]ethano­lato-1:2κ(2) O:O}dicopper(II)

The title compound, [Cu(2)(C(5)H(7)N(2))(C(4)H(10)NO(2))Cl(2)(C(5)H(8)N(2))], is a pyrazolate amino­alcohol complex which contains two di­methyl­pyrazole mol­ecules in monodentate and bidentate-bridged coordination modes and a monodeproton­ated di­ethano­lamine mol­ecule. Both copper atoms are involved in the formation of non-planar five-membered chelate rings. One Cu atom is in a distorted tetra­hedral environment formed by the pyridine nitro­gen atom of the protonated di­methyl­pyrazole mol­ecule, the N atom of the deprotonated bridged di­methyl­pyrazole, the Cl atom and the bridged O atom of the monodeprotonated di­ethano­lamine. The second Cu atom has an inter­mediate environment between trigonal bipyramidal and square pyramidal, formed by the N atom of the deprotonated bridged di­methyl­pyrazole, the Cl atom and the N atom of the amino­alcohol, and two O atoms of the deprotonated and protonated OH groups. In the crystal, N—H⋯Cl hydrogen bonds link the molecules into anti­symmetric chains running along the a-axis direction. Adjacent chains are connected by O—H⋯O hydrogen bonds involving the hydroxyl group as donor.
