Synthesis and X-ray structure of [RuCo3(µ-CO)2(CO)7(µ-PPh2)(µ4-η2-ButC
CH)]: a novel heteronuclear butterfly cluster via the fragmentation of a phosphinoalkyne
Abstract
The dehalogenation of [RuCl2(Ph2PC
CBut)(p-cymene)](1) by Co2(CO)8 and subsequent protonation afford the mixed metal cluster [RuCo3(µ4-η2-ButC
CH)(µ-PPh2)(CO)9](2) for which an X-ray structure determination has established the butterfly configuration of the RuCo3 species.
