Synthesis and molecular structures of Co2(CO)6−n(PPh3)n[μ-C2(CH2R)2] (R=CH2OH or CH2SCMe3) derivatives containing chelated [CpFe(CO)2]2Sn or W(CO)4 fragments

Reaction of [Co2(CO)6][μ-C2(CH2OH)2] with [CpFe(CO)2]2Sn(OMe)2 or interaction of [Co2(CO)5(PPh3)][μ-C2(CH2SCMe3)2] with W(CO)5(THF) gives mixed-metal chelate derivatives [Co2(CO)6][μ-C2(CH2O)2]Sn[CpFe(CO)2]2 and [(Ph3P)Co2(CO)5][μ-C2(CH2SCMe3)2][W(CO)4], respectively, characterized by X-ray diffraction analysis.
