The facile oxidation of 6,12-dihydrodipyrido [1,2-alpha1',2'-d] pyrazidinium (DDP2+ = [C12H12N2]2+) chloride to cyclic quaternary ammonium monocation, 12-oxo-9H-dipyrido[1,2-alpha;1',2'-d]pyrazin-5-ium (ODP1+ = [C12H9N2O]1+) is achieved when it reacts with [M(mnt)2]2- (M=Ni2+ and Cu2+) resulting in the formation of the ion pair compounds [ODP]2[Ni(mnt)2] (1) and [ODP]2[Cu(mnt)2] (2), respectively (see Scheme 1 for the structures of [ODP]1+ and [DDP]2+). The nickel complex 1 exhibits intense emission at room temperature in the visible region, whereas, in the case of copper analogue 2, the emission gets quenched. The oxo cation ODP (known to be an unstable species and never characterized unequivocally before) is stabilized in 1 and 2 by cation-anion interactions.
