Abstract
Trans-potassium-bis(oxalate-O,O)-diaqua-chromium(Ⅲ)-trihydrate, a ever reported Chromium(Ⅲ) complex, was synthesized and its more precise structure was re-defined by more advanced X-ray diffractometer and analysis methods. It crystallized in monoclinic, space group P2/n (No. 13), with a = 7.8827 (4) ?, b = 5.7296(3) ?, c = 13.6447(7) ?, ?= 103.506(5)°, Z = 2, Dc =1.980 Mg/m3, V = 599.22(5) ?3. Thermal analysis experiment reveals the complex keeps its thermal stability till about 357 K. Under ultraviolet radiation of 410 nm, a sharp emissions locating at about 610 nm was found.关键词
