Black crystals were formed from reductive electrocrystallization of [Ru(terpy)2](PF6)2 (where terpy = 2,2':6',2'-terpyridine) from an acetonitrile solution containing 100 mM TBAPF6. X-ray analysis shows that such crystals are composed exclusively of Ru(terpy)2]0 (1) which happens to be structurally very similar to the parent [Ru-(terpy)2]2+. Lattice that does not have solvent or counteranion was observed from the black crystals.

A four-probe single-crystal conductivity method and powder static magnetic susceptibility measurements help study (Ru(bpy)3)(0) polycrystals. A low temperature sub-curie tail and a broad maximum at 300 Kelvin suggest a one dimensional chain behavior. The neutral molecules are closely packed allowing strong intermolecular pi*-pi* overlap, consistent with a spin-1/2 alternating linear axis Heisenberg antiferromagnetic model. The crystal is highly conducting along the needle axis probably through a variable range three dimensional hopping mechanism. This complex does not represent a true 'expanded atom' model as the electrons from the cations are not completely delocalized.

The redox properties of Na+, Ca2+ and La3+ cryptates of tris(bipyridyl) (1-Na+, 1-Ca2+, 1-La3+) and Na+ complexes of five ligands were determined by cyclic voltammetry in DMF solution. The cyclic voltammograms of 1-Na+, 1-Ca2+ and 1-La3+ were similar containing three reducible ligands resulting to three, evenly spaced and quasi-reversible redox couples. There was only one reducible ligand for 2-Na+ and for 6-Na+ which resulted to an anticipated one redox wave.

C(sub 60)(super 6-) and C(sub 70)(super 6-) in acetonitrile/toluene solvent system at -10 degrees celsius were studied using differential pulse and cyclic voltammetry at very slow scan rates. The results indicated the first reversible production of C(sub 60)(super 6-) from the reduction of fullerenes and the first stable monitoring of C(sub 70)(super 5- and 6-) fullerenes in solution.
