Six new butterfly Fe/S cluster complexes, (mu-RS)(eta(1)-Ph2PS-eta(1))[Fe-2(CO)C-6] (3, R = Me; 5, R = Ph), (mu-RS)(eta(1)-Ph2PS-eta(1))[Fe-2(CO)(5)(Ph2PY)] (4, R = Me, Y = Cl; 6, R = Y = Ph), and (mu-RS)(eta(1)-Ph2PS-eta(2))[Fe-2(CO)(6)](mu(4)-S)[Fe-2(CO)(5)] (7, R = n-Bu; 8, R = Ph), were unexpectedly prepared by a "one-pot" synthetic method involving reactions of the in situ generated S-centered monoanions (mu-RS)(mu-S-)Fe-2(CO)(6) (1) and (mu-RS)(mu-S-)-[Fe-2(CO)(6)](2)(mu(4)-S) (2) with Ph2PCl. While the possible mechanisms for the unexpected reactions are suggested, the structures of products 3-8 have been fully characterized.
