Intramolecular hydrogen-bonding stabilisation of tetrafluoroborate co-ordination to copper(II): crystal structure of (2,2′-bipyridine)bis(2-cyanoguanidine)bis-(tetrafluoroborato)copper(II)

Abstract

(2,2′-Bipyridine)bis(2-cyanoguanidine)bis(tetrafluoroborato)copper(II), in which tetrafluoroborate co-ordination is stabilised by an intramolecular N–H ⋯ F hydrogen bond, has been isolated from aqueous solution and structurally and spectroscopically characterised.
