The odd-electron compounds [M(bpy)2(L1)](ClO4) M = Ru ([1](ClO4)) or Os ([2](ClO4)), and the even-electron species [M(bpy)2(H2L2)](ClO4)2, M = Ru ([3](ClO4)2) or Os ([4](ClO4)2) were obtained from pyrene-4,5-dione, L1, or 4,5-diaminopyrene, H4L2, and were characterised structurally, electrochemically and spectroscopically. Experimental and computational analysis (TD-DFT) revealed rather different electronic structures and spin distributions of the paramagnetic monocations 1+-4+.
