Hydrothermal reaction of diethyl 2-(2-cyanoethyl) malonate, ZnCl2, NaN3 and NaOH yielded a new 1H-tetrazolate-5-butyrate coordination polymer, [Zn(tzb)]n (1) (H2tzb = 1H-tetrazolate-5-butyric acid), which presents a 3-D noninterpenetrating diamond network. The in situ generated tzb2− ligand adopts a μ4-bridging mode with carboxylate group in a syn–anti fashion and tetrazolate group in a 1,4-N manner. Polymer 1 exhibits a weak second-order nonlinear optical coefficient about 0.5 times that of potassium dihydrogen phosphate (KDP), and also displays strong blue photoluminescence at room temperature and a high thermal stability up to 400 °C.
Graphical abstractThe first coordination polymer based on the bifunctional ligand 1H-tetrazolate-5-butyric acid (H2tzb), which presents a 3-D diamond network, was obtained by in situ ligand synthesis reactions from the organic precursor of diethyl 2-(2-cyanoethyl) malonate under hydrothermal condition.Figure optionsDownload full-size imageDownload as PowerPoint slideResearch Highlights► The first polymer based on 1H-tetrazolate-5-butyric acid ligand. ► The acentric polymer exhibiting a diamond network and nonlinear optical effect. ► A good candidate for efficient blue emission materials. ► A high thermal stability up to 400 °C.
