Synthesis and Solid Fluorescence Properties of Novel Strontium Complex Containing 5-(2-Pyrazinyl)-1H-tetrazole
Strontium complexes have attracted the interest of many researchers because of their excel-lent catalytic activity and fluorescence properties.In this manuscript,A novel mononuclear complex{[Sr(L)2]·2H2 O}n(I)was synthesized by solvothermal synthesis using strontium chloride as metal source,5-(2-pyrazinyl)-1H-tetrazole(HL)and piperic acid(HL1)as ligands in DMF-water system.The structure was characterized by EA,SXRD,PXRD,IR and TGA.The single crystal X-ray diffrac-tion results show that complex I belongs to the monoclinic crystal system P21/n space group and Sr at-oms displays a slightly twisted octahedral environment,while the pepper acid is not involved in coordi-nation environment.The 2D supramolecular structure is formed by the intermolecular O—H···N hydrogen bond.Solid fluorescence study shows that complex I have well fluorescence properties with a maximum emission wavelength of 450 nm(λex =223 nm),indicating that I is a potential blue light material.
