Abstract

The reaction between 1,3-bis(diphenylphosphinite)-benzene and Os3(CO)10(MeCN)2 affords complex Os3(CO)10[1,3-(PhPO)2C6H4]. A thermolysis of this cluster in refluxing toluene results in the activation of O–PPh2 and C–H bonds and the formation of unsaturated triosmium cluster Os3(μ-H)(μ-PPh2)(CO)7[(C6H3(O)(OPPh2)] that possesses a remarkable structure with the pseudo-pincer ligand containing a bridging μ-η1-aryl group.
