Abstract: | Two new silver(I) complexes Ag(barb)(pym)]·H2O (1) and Ag(barb)(dmpy)]·1.5H2O (2) (barb = 5,5-diethylbarbiturate, pym = pyridine-2-ylmethanol and dmpy = 2,6-dimethoxypyridine) have been synthesized and characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction. In both complexes, the silver(I) ions are linearly coordinated by the N atoms of a barb anion and a pym or a dmpy ligand, forming mononuclear species. The molecules of 1 and 2 are doubly bridged by N–HO hydrogen bonds involving the barb moieties and these hydrogen-bonded dimers are assembled into two-dimensional layered networks through weak AgCpy (η1) interactions of ca. 3.3 Å. Additionally, the thermal and fluorescent properties of these complexes are also investigated. |
