• Complexes having three different metal atoms have been prepared by reacting 1,1′-bis(thiocyanatomercurio)ferrocene with M(NCS)<SUB>2</SUB> [M=Mn(II), Co(II), Ni(II), Cu(II), Zn(II)]. The complexes have been referred to as Lewis acid and have molecular formula Fe(C<SUB>5</SUB>H<SUB>4</SUB>HgSCN)<SUB>2</SUB>M(NCS)<SUB>2</SUB>. They have unsaturation at M, hence have been reacted with nicotinamide and 2,2′-bipyridyl and adducts of molecular formula Fe(C<SUB>5</SUB>H<SUB>4</SUB>HgSCN)<SUB>2</SUB>M(NCS)<SUB>2</SUB>L<I><SUB>x</SUB></I> [<I>x</I>=2 when nicotinamide and 1 when bipyridyl] have been isolated. The Lewis acids and the adducts have been characterized by elemental analysis, molar conductance, magnetic moment, infrared and electronic spectral studies. These studies reveal that the coordination geometry of M is tetrahedral in the Lewis acids of cobalt, zinc, and manganese. The geometry around M in the Lewis acids of nickel and copper is octahedral through axial bonding. The adducts have a bridged structure and the geometry around M is octahedral. Quantitative softness parameters have also been applied to derive certain information.
