Four tetrairidium carbonyl clusters linked by six diphosphino ligands: synthesis and X-ray structure of [{Ir(4)(CO)(9)}(4)(dppmb)(6)] (dppmb = 1,4-bis(diphenylphosphinomethyl)benzene.
Tetrairidium carbonyl clusters are potentially useful connectors for multidimensional functionalized frameworks with organic bis-phosphines as linkers. The reaction of Ir(4)(CO)(12) and 1,4-bis(diphenylphosphinomethyl)benzene produces an oligomeric cyclic structure, made of 4 connectors and 6 linkers, a possible intermediate in the formation of three dimensional networks.
