PMe2Ph a or PEt3b) gave five-co-ordinatecomplexes [[graphic omitted]Ph2)-2}2L] without cleavage of the Ni–P bond of the ring. Stabilization of the four-membered ring is achieved when two bidentate ligands are present or in the five-co-ordinate compound [[graphic omitted]Ph2)-2}(dppm)2]. Two bidentate ligands are also needed to stabilize the formation of five-co-ordinatecomplexes. The molecular structures

A series of phosphines incorporating (C6Cl5) substituents, Ph2P(C6Cl5) 1, PhP(C6Cl5)22, P(C6Cl5)33 and (C6F5)P(C6Cl5)24 were prepared. In the case of 1, 2 and 4, these were converted to the corresponding aryl-difluorophosphoranes 5–7via reaction with XeF2, whereas reaction of 3 with XeF2 afforded only an inseparable mixture of products. The compounds 5–7 were converted to the fluorophosphonium cations
