Abstract
The invention discloses a 5-aminoorotic acid dinuclear cadmium complex. The 5-aminoorotic acid dinuclear cadmium complex is characterized in that the complex is prepared from a cadmium salt, an orotic acid derivative and 2,2'-bipyridine through a hydrothermal method; the complex has a definite space structure and an accurate molecular formula; and synthesis steps are simple. The constitutional unit of the complex comprises two metallic cadmium ions, two 5-aminoorotic acids, one oxalate ions, two 2,2'-bipyridines, two coordination water molecules and four object water molecules; the molecular formula of the complex is C32H36N10O18Cd2; the complex belongs to a triclinic system; the space group of the complex is P-1; and cell parameters are that a is equal to 8.8941 angstrom, b is equal to 9.2338 angstrom, c is equal to 13.759 angstrom, alpha is equal to 97.978 DEG, beta is equal to 97.975 DEG and gamma is equal to 116.416 DEG. The prepared complex is a purple fluorescent material, has excellent physicochemical performance and shows wide application prospects in the field of photoelectric materials or catalytic materials.
Description
technical field [0001] The invention belongs to the field of structural chemistry, in particular to a 5-aminoorotate dinuclear cadmium complex. Background technique [0002] In recent years, supramolecular chemistry and crystal engineering of coordination compounds have attracted great interest due to their diverse structures and potential applications. Orotic acid, also known as vitamin B 13 , as a new type of vitamin, in Japan, it is mainly used as an ingredient of over-the-counter multivitamins and as an additive for refreshing drinks; in Western Europe, it is not only a composition of medicinal vitamins, but also widely used in cosmetics. As a nutritional cosmetic matrix, it can It is well absorbed by skin cells, promotes the metabolism of human cells, and obviously inhibits skin aging; in the United States, people have done more research on orotic acid and its derivatives, and their uses are relatively wide, in the fields of medicine, food, daily chemicals, and life sc...
