Reactivity of three novel Pd germylene species is presented. (Et3P)(2)PdGe[N(SiMe3)(2)](2) (1) and (dppe)PdGe[N(SiMe3)(2)](2) (6) react with COS to give the sulfide bridged species (Et3P)(2)Pd(muS)Ge[N(SiMe3)(2)](2) (2) and (dppe)Pd(muS)Ge[N(SiMe3)(2)](2) (7) (dppe = (diphenylphosphino)ethane). (Ph3P)(2)PdGe[N(SiMe3)(2)](2) (4) reacts with COS to give the disulfide bridged complex (Ph3P)(2)Pd(US)(2)Ge[N(SiMe3)(2)](2) (5) resulting in Pd-Ge bond cleavage. This phosphine dependent reactivity is explored. Crystal structures of 2, 5, 7, and the dimeric form of complex 2, {(Et3P)-Pd(muS)Ge[N(SiMe3)(2)](2)}(2) (8), are reported. In the presence of excess germylene, complexes 2 and 5 are shown to partially regenerate their parent palladium germylene complexes, 1 and 4, respectively, via photolysis or heating.
