supramolecular self-assembly structures of one tetranuclear silver(I) complex and three silver(I) coordination polymers derived from bis-bidentate imino-pyridine ligands and their reduced N-methyl derivatives are discussed. Six new ligands were synthesised, and the X-ray structural analysis of L1, L2 and L5 with silver(I) ions indicated the formation of 1D coordination polymers, namely [AgL1]BF4}n (1), [AgL2]ClO4}n
