• Cobalt(II), nickel(II), and copper(II) complexes with dioximes substituted by BF<SUB>2</SUB>- and B(C<SUB>2</SUB>H<SUB>5</SUB>)<SUB>2</SUB>-groups for bridging hydrogen atoms were prepared. The BF<SUB>2</SUB>-substitution caused a red-shift of d-d band and increase of <I>g</I><SUB>⁄⁄</SUB>-value for copper(II) complexes and positive shift of polarographic half wave potential of nickel(II) complexes. In the case of the B(C<SUB>2</SUB>H<SUB>5</SUB>)<SUB>2</SUB>-substituted complexes, such variations were not observed. The BF<SUB>2</SUB>-substituted cobalt(II) complexes are stable under an open atmosphere at room temperature in a solid state and in a DMF solution. These were interpreted in terms of the electron-withdrawing ability of BF<SUB>2</SUB>-group in the ligand.
