Two-dimensional supramolecular networks generated from weak Ag⋯Cpy interactions: Synthesis, structural, thermal and fluorescence studies of silver(I) complexes of 5,5-diethylbarbiturato with pyridine-2-ylmethanol and 2,6-dimethoxypyridine

[Ag(barb)(pym)]·H2O and [Ag(barb)(dmpy)]·1.5H2O complexes (barb = 5,5-diethylbarbiturate, pym = pyridine-2-ylmethanol and dmpy = 2,6-dimethoxypyridine) have been synthesized and characterized. The molecules of both complexes are doubly bridged by N-H⋯O hydrogen bonds and the hydrogen-bonded dimers are extended into 2D networks through weak Ag⋯Cpy (η1) interactions.
