Aquabis(2,2′-bipyridine-κ2N,N′)copper(II) bis(tetrafluoridoborate)

Abstract

In the title compound, [Cu(C10H8N2)2(H2O)](BF4)2, the CuII atom is coordinated by four N atoms and one O atom in a distorted trigonal–bipyramidal geometry. The Cu—N bond lengths are in the range 1.982 (3)–2.124 (3) Å, while the Cu—O distance is 2.035 (4) Å. The structure is stabilized by O—H⋯F hydrogen bonds between the CuII complex and the tetra­fluoridoborate anion. The F atoms of one anion are disordered over two positions; the site occupancy ratio is ca 3:2.
