Abstract:	The synthesis, characterization and structure of new cobalt and nickel complexes with a BF2+ bridged, bis (1,2-dione dioxime) ligand based on benzoquinone are described. The crystal structure of the bis (BF2+) bridged nickel complex has space group C2/c (#15) with unit cell dimensions a = 19.000 (2), b = 5.452 (2), c = 16.357 (1) A,Beta = 119.251 (7)degrees, V = 1519.8 (2) A(3), Z = 4, R-i = 0.043 and wR(2) = 0.052. The ligand provides strong field and the complexes are diamagnetic. The spectral properties of the complexes are discussed.
