Reaction of Rh(I)dimethylglyoximato monoanion (Hdmg)2 with small cone angle phosphines leads to reduction of one of the four equatorial oximes to an imine group. Four nonequivalent nitrogen atoms in the reaction product (Rh(III)(Hdmg)2,3-butanedione 2-imine 3-oximato (Hbdio)(PR3)2)+ connect the ligands Hdmg and Hbdio to Ru(III). Two phosphines in the trans positions complete the metal coordination sphere. X-ray crystallographic studies help determine the structure of the complexes, and polarographic and cyclic voltammetric studies enable the investigation of the electrochemical properties of the complexes.

The reaction of methylaquobis(dimethylgyoximato)cobalt(III) with 3-pyridylboronic acid in CH2Cl2/CH3OH led to the formation of a dinuclear complex that contained two methylcobaloxime units. The methylcobaloxime units of the resulting dinuclear complex were held together by two B(OCH3)(3-Py) residues which were very stable in solution. Furthermore, dimer was arranged around a crystallographic symmetry center.
