Syntheses, Structures, and Blue Luminescent Properties of 2,6-Bis (benzimidazolyl) Pyridine and Its Mercury Complex

摘要

A novel blue luminescent mercury(Ⅱ) complex of 2,6-bis(benzimidazolyl)pyridine( L ) was synthesized. In solid state, this complex has the formula [Hg( L )Cl2]52DMF([STHZ]1[STBZ]). The molecular structures of both the ligand and the complex were determined by using single-crystal X-ray diffraction. Crystallographic studies of the mercury(Ⅱ) complex reveal that the complex possesses a five-coordinated geometry that can be best described as a distorted trigonal-bipyramidal. The luminescent properties of ligand L and complex [STHZ]1[STBZ] both in solution and in solid state were also studied.
