Аннотация: 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.

Ключевые слова: pincer complexes, pseudo-pincer ligand, osmium cluster, NMR, single crystal X-ray analysis.
