Abstract

Complexation of AgNO3 with L, where L is urea (Ur), N,N’-dimethylurea (DMUr), and acetamide (AA), in aqueous solution is studied. Three new coordination polymers, [Ag(AA)(μ-NO3)2]n (I), [Ag2(μ-DMUr)(μ-NO3)2]n (II), and [Ag2(μ-Ur-O,N)2(μ-NO3)2]n (III) are isolated and characterized by X-ray diffraction. Silver coordination surrounding is described with the DFT and QTAIM methods. Bond strength and features of Ag(I) interaction with L and nitrate ligands are estimated. Thermal properties of I–III are studied. On the basis of the TGA data, a probable mechanism of thermal destruction is suggested.
