The chlorination of one (WP) bond of [(CO)4W(η4-P4W(CO)5}4)] is observed on reaction with PCl5 in CH3CN. The dichloro derivative [(CH3CN)2(CO)2WCl}(η3-P3W(CO)5}2P(Cl)W(CO)5})] is easily transformed into the more stable phosphahydroxy complex [(CH3CN)2(CO)2WCl}(η3 -P3W(CO)5}2P(OH)W(CO)5})]. The “butterfly” type P4-ring coordinates as a η3-P4 ligand to a capping [(CH3CN)2(CO)2WCl] unit. Only three
