Novel cyclic hexanuclear complexes containing quadruply bonded units joined by μ6-carbonate ions

Abstract
Three complexes {[trans-Mo2(O2CCF3)2(µ-dppa)]36-CO3)(µ2-X)3}F [X = Cl, Br or I; dppa = N,N-bis(diphenylphosphino)amine], are reported, which are the first cyclic, hexanuclear complexes containing quadruply bonded units joined by carbonate ions.
