Dimers of delocalized Ru3O clusters linked by ortho-metallated 2,2′-bipyrimidine in μ4-η1(C),η1(C),η2(N,N),η2(N,N) mode†
Abstract
A remarkable cluster–cluster interaction is operative in dimers of delocalized Ru3O(OAc)5(py)2 clusters with ortho-metallated 2,2′-bipyrimidine (bpym) in an unprecedented μ4-η1(C),η1(C),η2(N,N),η2(N,N) bonding mode; interconversion of the dimeric species [{Ru3O(OAc)5(py)2}2(μ4-bpym)]n+ (n = 0, 1 or 2) with different charges is attainable by chemical
