Abstract The title compounds were prepared from chloro(organophosphine)metal(I) complexes and the urea homologues SeC(NH2)2 and SC(NHMe)2 in good yields. Recrystallization of [Ph3,PAg{SeC(NH2)2}]+Cl- from DMF/CH2Cl2 leads in low yield to the dinuclear complex [{µ2-SeC(NH2)2}Ag{SeC(NH2)2}2]22+2Cl- • 4DMF. The crystal structure reveals short Ag-Ag contacts and unexpectedly acute angles at the bridging selenium atom. The crystal structure of [Ph3PAu{SC(NHMe)2}]+Cl- • SC(NHMe)2 shows short N•••Cl and N•••S contacts that probably correspond to hydrogen bonding.
