Reactions of substituted 1,2,3-selena- and thia-diazoles with (η5-C5H4R)Mn(CO)2THF, R H, Me, lead to isolable blue complexes in which THF is replaced by the diazole ligand. The X-ray structure of the benzothiadiazole complex is reported and shows the intact diazole bonded via N2 to manganese. Ab initio calculations on 1,2,3-thiadiazole generated a structure and protonation energies that confirm N2
取代的1,2,3- selena-的反应和硫杂二唑类与(η 5 -C 5 H ^ 4 R)的Mn(CO)2 THF,RH,Me中,铅以可分离的蓝色络合物,其中THF被替换二唑配体。据报道,苯并噻二唑配合物的X射线结构表明完整的二唑通过N 2与锰结合。从头算对1,2,3-噻二唑的计算产生了结构和质子能,这些能量和能量证实了N2为配位点,并且还预测了配位时的显着结构变化。然而,测定了游离的苯并-1,2,3-噻二唑的结构,并且在配位时没有显示出明显的结构变化。类似地,确定了4-苯基-1,2,3-噻二唑的结构,并显示出与W(CO)5取代的配体相同的结构参数。
