5-trimethyl-phenyl)phosphite] has been obtained by reacting [C 12 H 10 Cr(CO) 3 ] with the phosphite in UV light. The complex has been characterized by elemental analysis, 1 H NMR and 13 C NMR spectra, and X-ray analysis. Crystals are orthorhombic, space group Pbca , Z = 8, with the cell dimensions a = 22.067(1), b = 17.563(1), c = 18.784(1) A. Owing to the steric requirements the phosphite is located opposite
摘要通过使[C 12 H 10 Cr(CO)3]与亚磷酸酯在紫外光下反应,制得化合物[ac-Cr(CO)2-三(2,3,5-三甲基-苯基)亚磷酸酯]。该复合物已通过元素分析,1 H NMR和13 C NMR光谱以及X射线分析进行了表征。晶体是正交晶体,空间群Pbca,Z = 8,晶胞尺寸a = 22.067(1),b = 17.563(1),c = 18.784(1)A。由于空间要求,亚磷酸酯位于与2,的三个非键环和三个3,3,5-三甲基苯基的CrPO角彼此明显不同(115.2、120.9和121.8°)。
