Three novel coordination compounds were successfully isolated using rare and poorly studied 5-phenyl-2,2′-bipyridine (LI) and completely unexplored 6-phenyl-3-(pyridin-2-yl)-1,2,4-triazine (LII) ligands with AgNO3, namely, [Ag(LI)2]NO3·0.5H2O (1), [Ag(LI)PPh3NO3]·0.5CH2Cl2 (2), and [Ag2(LII)2(H2O)2](NO3)2 (3). 1 can be converted into 2 upon reacting with PPh3, while no conversion was observed for 3. The formation of 3 was templated through anion−π-system interactions between the NO3 anions and the electron deficient 1,2,4-triazine ring of LII, which play a crucial role in the supramolecular assembly.
