The title compound, [Ru(C12H7Br2N2)2(CO)2], possesses a
distorted octahedral environment about the Ru atom, with
two cyclometallated 4,40-dibromoazobenzene ligands and two
mutually cis carbonyl ligands. The donor atoms are arranged
such that the N atoms are respectively trans to a carbonyl
ligand and an aryl C atom.
Comment
The title compound, (I), has been prepared as a minor product
of the reaction of Ru3(CO)12 and 4,40-dibromoazobenzene in
refluxing n-octane; the major product is the cluster complex
Ru3(3-NC6H4Br)2(CO)9 (Willis et al., 2005). Two strong
(CO) absorptions at 2039 and 1991 cm1 in the IR spectrum
of (I) are consistent with the presence of two mutually cis
carbonyl groups. The crystal structure was investigated to
ascertai
