New structural motifs for main group or transition metal phosphanediyl clusters are obtained for the title compounds 1, 2, and 3. They are synthesized by complex Brønsted acid–base reactions of the corresponding primary silylphosphanes and inert stannanediyl derivatives or [{CuOtBu}4]. None of the three compounds needs terminal donor ligands on the metal centers to aid stability. R = triorganosilyl.
