✦ Synopsis

The monomeric phosphanylgallanes R,GaPR'R (R = tmp, crystal structures of tmpzGaPtBuz, Mes2GaPtBu2, Mes-Mes; R' = H, tBu; R = Mes, tBu), the diphosphanylgallane Ga(PtBuz),, and [tmp2GaP(tBu)lz confirms the monomeric na-Me~Ga(ptBu,)~, and diphosphandiylbisgallane [tmp,GaPture of these molecules. The gallium-phosphorus bond (tBu)lz have been synthesized from alkali metal phosphides lengths are found to be 237.5, 233.5, 235.4 pm (averaged), and substituted gallium chlorides. Low-temperature NMR and 242.3 pm, respectively, with all phosphorus atoms being studies of the phosphanylgallanes reveal no barrier to rota-pyramidally coordinated. tion about the gallium-phosphorus bond.

## Abstract Monomeric (M = 2Li or 2H) and polymeric (M = 2H, Zn, Cu, Co, or Ni), where M is metal or hydrogen, phthalocyanines were prepared by the tetramerization reaction of bisphthalonitrile monomer with appropriate materials. The electrical conductivities of the polymeric phthalocyanines, which
