Abstract:

Using diethylenetriamine(DETA) as ligand, a five-coordinated zinc complex [Zn(OAc)2·(DETA)]·H2O was synthesized. The structure of the complex was characterized by elemental analysis, infrared spectroscopy(IR) and X-ray single crystal diffraction(XRD), and the catalytic performance and the mechanism in catalyzing Henry reaction were studied. The results show that the complex belongs to monoclinic crystal system, space group P21/c. The central zinc atom is coordinated with three nitrogen atoms and two oxygen atoms, forming a distorted triangular bipyramidal configuration, then a three-dimensional crystal structure is further formed through intramolecular and intermolecular hydrogen bonds. In the optimized conditions, the complex plays a good catalytic performance upon Henry reaction, and the reaction substrates of different aldehydes are universal to a certain extent.
