An understanding of the photophysical processes in dipyridophenazine complexes of ruthenium(II) is necessary to further develop similar complexes as biological probes and chemical sensors. The effect of the ancillary ligands on the photophysical properties of monodipyridophenazine complexes of ruthenium(II) could assist in explaining the photophysical properties of these complexes and could also provide more insight into the light switch effect for [Ru(bpy){sub 2}dppz]{sup 2+} and [Ru(phen){sub 2}dppz]{sup 2+}. The authors have been exploring the effect of strong-field ligands such as NH{sub 3} and CN{sup {minus}} on the Ru-dppz fragment. In this note they report the synthesis and characterization of Ru(acac){sub 2}dppz, the first neutral Ru-dppz complex to their knowledge, and solvatochromism in its charge-transfer transitions.
