[(η5-C5Me5)2Ti]2(µ-OC)2[cpMo(CO)]2(cp =η5-C5H5): A compound with linear co-ordination of titanium to a bridging carbonyl and a d6–d6[cpMo(CO)2]2 fragment

Abstract

Reaction of (η⁵-C₅Me₅)₂ Ti-neo-C₅H₁₁ with [cpMo(CO)₂]₂(cp =η⁵-C₅H₅) yields the title compound (1); X-ray analysis of (1) shows a 4e (σ,π) Ti–O interaction, resulting in a novel linear co-ordination of titanium to a bridging carbonyl and a new geometry of a [cpMo(CO)₂]₂ fragment caused by a d⁶–d⁶(Mo–Mo) electron count.
