ABSTRACT
A series of photo triggered {RuCl2(CO)2} carbon monoxide releasing
molecules was synthesized from {[RuCl2(CO)3]}2 and benzimidazol
derivatives (N-N), functionalized with different electron-donating and
withdrawing groups, to afford octahedral complexes of the type cis-/trans-
[RuCl2(CO)2(N-N)]. The structures of the metal carbonyl complexes were
elucidated using different analytical and spectroscopic tools. The
geometrical stereochemistry around the metal ions was assigned by IR
spectroscopy and quantum chemical calculations. The dark stability in
aerated DMSO and the photoactivatable CO release properties were
investigated. With the aid of time-dependent density functional theory,
the influence of the substituent (type and position on the phenyl ring) on
the nature of the lowest energy transition was investigated.
