This article describes the low-temperature photochemistry of the complexes Ni(CO)2(tBu-DAB) (I) and Ni(CO)2(2,6-iPr2Ph-DAB) (II) in different media, in both the absence and the presence of a substituting ligand. The complexes differ in their molecular structure and in the character of their lowest MLCT transitions. The results of this study show that these differences are also responsible for the different primary photoprocesses taking place upon low-energy excitation. Irradiation into the MLCT bands causes breaking of a metal-nitrogen bond in the case of complex I and loss of CO for complex II.
