  • Abstract
    The title compound, [Cu2(C5H7N2)(C4H10NO2)Cl2(C5H8N2)], 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.
