Tetrakis(pyridine-κN)bis(tetrafluoridoborato-κF)copper(II)

Abstract

In the title complex, [Cu(BF4)2(C5H5N)2], the CuII ion is in an octahedral coordination environment and is surrounded by four pyridine and two tetrafluoridoborate molecules. The four pyridine molecules are coordinated to the copper ion through their N atoms in the equatorial plane and display a right-handed screw arrangement around the CuII ion. The remaining two trans positions in the octahedron are occupied by the BF4− anions, each coordinating weakly through an F atom. The crystal packing shows a two-dimensional sheet structure parallel to the ab plane that is formed by C—H...F hydrogen-bonding interactions.
