Abstract: The solvothermal reactions of 2,6-bis(1H-benzimidazol-2-yl)pyridine (H2bpp) and hydrated ZnCl2 in the presence of pyridine-2,4-dicarboxylic acid (2,4-pdcH2) or pyridine-2,5-dicarboxylic acid (2,5-pdcH2) afforded the title one-dimensional linear compounds, [Zn(C7H3NO4)(C19H13N5)]n or [Zn(2,4-pdc)(H2bpp)]n, (I), and [Zn(C7H3NO4)(C19H13N5)]n or [Zn(2,5-pdc)(H2bpp)]n, (II), respectively. The ZnII cations in these compounds have closely comparable geometries and both are octahedrally coordinated by N4O2 donor sets. The thermal stabilities have been investigated by thermogravimetric analysis (TGA) on the crystalline samples and their solid-state photoluminescence properties have been investigated at room temperature.
Formula: [Zn(C7H3NO4)(C19H13N5)] and [Zn(C7H3NO4)(C19H13N5)]
