We describe here the synthesis of heteroleptic organogermylenes containing a sulfoxide donor function for their application in coordination chemistry. While complexation reaction with [W(cod)(CO)4] and [Mo(nbd)(CO)4] afforded bis(germanium)(II) transition-metal complexes, a bidentate complex coordinated by germanium(II) and the oxygen atom of the sulfinyl group was obtained from [Ru(PPh3)3Cl2].
