[RuC(Me)C(Ph)PEt3}(CO)2(η5-7,8-C2B9H11)] (4b) and [RuC(Me)C(Ph)P(Ph)2CH2PPh2}(CO)2(η5-7,8-C2B9H11)] (4c), respectively. The structure of 4b was established by an X-ray diffraction study which revealed that the PEt3 molecule was attached to the carbon atom of the CPh group. In contrast, reactions between 3c and the donor molecules AsPh3, SbPh3 and Ph2P(S)CH2P(S)Ph2 resulted in displacement of the alkyne
