The syntheses of new stable bivalent germanium, tin and lead homoleptic species (ArO)(2)M: (ArO = 2,4,6-[(CH3)(2)NCH2]3C6H2O; M=Ge (1), Sn (2), Pb (3)), Ge(OSO2CF3)(2) . C4H8O2 (4) and heteroleptic species M(OAr) [N(SiMe(3))(2)] (M = Ge (5), Sn (6)) are described. New organometallic heterocycles, stable metalla-imines and germathione (ArO)(2)M = X (X = NSiMe(3), S) and metal(II)-transition metal complexes are obtained starting from 1 and 2.
