Reaction of (m-Me2CHS)(m-PhCH2S)Fe2(CO)6 with excess PPh3 in boiling toluene for 6 h gave (m-Me2CHS)(m-PhCH2S)Fe2(CO)4(PPh3)2 (I). The crystal of I is triclinic, P1, with a 10.268(4), b 20.289(1), c 22.799(5) ? a 94.73(1), b 102.98(2), g 89.93(1)? Z = 4, R = 0.059 and Rw = 0.068. The cluster core of I consists of 2 Fe and 2 S atoms and has a butterfly structure. Two PPh3 ligands bonded to 2 Fe atoms are at the positions trans to Fe-Fe bent bond; Me2CH and PhCH2 groups are attached to different S atoms by equatorial bonds.
