The reaction of 1,1,2,3,3-pentamethyltrimethylenephosphinic acid cycP(O)OH and (C6H11)2P(O)OH with monoorganotellurium trichloride RTeCl3 (R = 2-phenylazophenyl) in benzene at room temperature afforded two pentanuclear complexes, [(RTe)4(TeO)(渭-O)6(cycPO2)2]路THF(1) [cycPO2 = 1,1,2,3,3-pentamethylene phosphinate] and [(RTe)4(TeO)(渭-O)6{(C6H11)2PO2}2]路2C6H6 (2). The reactions leading to the formation of 1 and 2 involve a Te鈥揅 bond cleavage. 1 and 2 are isostructural complexes and contain a Te4P2O6 macrocyclic framework that is part of a Te5O11P2 multi-metallacyclic framework. Both of these compounds contain a central inorganic Te鈺怬 connected to four other tellurium centers through four 渭-O bridges.
