Abstract :A novel Ag(I) dinuclear complex {[(C6H5)(C5H4N)-C=N-N=C- (C5H4N)(C6H5)]Ag}2.ClO4(ClO4) (1/2CH3CN) (1) that was derived under mild conditions, during the course of combination of AgClO4 with a polymorphic azine ligand, 1,4-diphenyl-1,4-bis(2-pyridyl)-2,3- diaza-1,3-butadiene (L) (condensed product of phenyl 2-pyridyl ketone and hydrazine monohydrate) is reported. The aforementioned complex is based on a central rotationally flexible diazine subunit (N-N). The azine ligand, L, having the N2 dinucleating fragment, provides a coordination focus for pairs of metal centres and ultimately leads to the formation of a 6-membered chelate ring in 1.
