Donor-stabilized bis(silylene)tungsten complexes CpW(CO)2{(SiMe2)···Do···(SiMe2)} (Cp = η-C5H5; Do = NEt2 (1), OMe (2)) were synthesized by photolysis of a C6D6 solution containing CpW(CO)3Me and HSiMe2SiMe2Do. The X-ray crystal structures of 1 and 2 revealed that the W−Si bonds (2.502(2) and 2.501(...
