The reaction of Ru3(CO)12 with five membered cyclic SP(S)(Fc)N(Ph)NC(Me) gave two novel trinuclear and tetranuclear ruthenium carbonyl clusters containing capping S atoms in Ru3(CO)8(μ 3 S)2[P(Fc)N(Ph)NC(Me)S] 1 and ...The reaction of Ru3(CO)12 with five membered cyclic SP(S)(Fc)N(Ph)NC(Me) gave two novel trinuclear and tetranuclear ruthenium carbonyl clusters containing capping S atoms in Ru3(CO)8(μ 3 S)2[P(Fc)N(Ph)NC(Me)S] 1 and Ru4(CO)7(μ CO)3(μ 4 S)2[P(Fc)N(Ph)NC(Me)S] 2 (Fc=C5H5FeC5H4).
