Dimers of delocalized Ru3O clusters linked by ortho-metallated 2,2 '-bipyrimidine in mu(4)-eta(1)(C), eta(1)(C), eta(2)(N,N), eta(2)(N,N) mode

摘要

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 mu(4)-eta(1)(C), eta(1)(C), eta(2)(N,N), eta(2)(N,N) bonding mode; interconversion of the dimeric species [{Ru3O(OAc)(5)(py)(2)}(2)(mu(4)-bpym)](n+) (n=0, 1 or 2) with different charges is attainable by chemical oxidation or reduction.
