Synthesis and crystal structure of a novel one-dimensional silver(I) complex with high urease inhibitory activity

A novel one-dimensional silver(I) complex, derived from 2-hydroxypyridine with Ag2O in an ammonia solution, have been prepared and structurally characterized. Each Ag atom in the complex is three-coordinate in a T-shaped geometry with two phenolate O atoms and one pyridine N atom. Adjacent Ag atoms are linked by Ag–Ag interactions, forming an Ag4 unit. The Ag4 units are further linked by four phenolate O atoms, forming a one-dimensional chain running along the c axis. The fluorescence of the complex has been studied. The complex show strong urease inhibitory activity.
