Synthesis, NMR and Single Crystal analysis of Novel 2,9-dimethyl-4,7- diphenyl(1,10)phenanthrolinediium

dimethyl-4,7-diphenyl(1,10)phenanthrolinediium was made available by acidifying of 2,9-dimethyl-4,7-diphenyl-1,10- phenanthroline in ethanol solvent using conc. HCl as acid. The bi-protonation of pyridine in phenanthroline was monitored by 1 H NMR and confirmed by X-ray single crystal, XRD structure of desired product was found to be a Monoclinic crystal system with C2/c1 space group and Z = 6.
