The new bis(phosphaalkenyl) germanium(II) compound (NHC)Ge(CClPMes*)2 reacts with L2M(CO)4 (M = Mo, W) to give bidentate complexes with an unexpected coordinating behaviour involving the Ge(II) centre and one phosphorus atom, and with AuI or Me2SAuCl to afford the monodentate complexes coordinated at the germanium(II) atom.
New 1,3-digermacyclobutanes, with two exocyclic CPMes* bonds, and the corresponding first bis(methylenethioxo)phosphoranes with CP(S)Mes* moieties have been synthesized.
