[5](ClO4)2. The redox properties of [4](ClO4)3 along with the precursor complexes, have been investigated. On exposure to visible light in the deoxygenated acetonitrile solution at room temperature both [4](ClO4)3 and [5](ClO4)2 spontaneously transform to their corresponding solvated derivative [RuII(dmdptz)(phen)(CH3CN)](ClO4)2 [2](ClO4)2 via the facile photocleavage of Ru–NO bond with KNO 9.26 × 10−3 min−1
