在四氢呋喃-甲醇介质中将环戊二烯基三羰基金属(钼或钨)氯化物与等摩尔羰基亚硝酰基钠盐在室温反应,产物经柱色谱分离和纯化得:橙色固体(η~5-C_5H_5)M(CO)_2NO、紫色固体[(η~5-C_5H_5)M(CO)_3]_2和黑色固体(η~5-C_5H_5)M(μ_3-NH)(μ_2-NO)(μ_2-CO)Fe_2(CO)_6(M=Mo或W)各两种.其中,后者是具有新颖结构的簇合物,分子中含有亚硝酰基(NO)被还原得到的亚胺基(μ_3-NH)配体.本文报道了它们的合成、表征和两种配合物X射线晶体结构研究的结果.
The cyclopentadienyl tricarbonyl metal (molybdenum or tungsten) chloride was reacted with the equimolar carbonyl nitrosyl sodium salt in tetrahydrofuran-methanol medium at room temperature. The product was isolated and purified by column chromatography to give an orange solid (η ~ 5 (Η_5-C_5H_5) M (CO) _3] _2 and black solid (η_5_C_5H_5) M (μ_3-NH) (μ_2-NO) CO) Fe_2 (CO) _6 (M = Mo or W), which is a new cluster with novel structure. The molecule contains the imine (μ_3- NH) ligands.The results of their synthesis, characterization and X-ray crystal structure studies of two complexes were reported.
