本文建议三核钼原子簇离子(Mo_3S_2Cl_9)~(3-)的生成步骤为:MoCl_2~(2+)与二核钼离子(Mo_2Cl_9)~(3-)首先加成产生[Mo_3(μ_3—Cl)_2(μ_2—Cl)_3Cl_6]~(11-),然后两个S原子取代三重桥联Cl原子。分子轨道计算支持了中间体(Mo_3Cl_(11))~-的可能存在。上述加成过程也适合于多核离子Mo_4Cl_(13)~+及Mo_6Cl_(15)~(3+)的形成。
It is suggested that the formation of [Mo_3S_2Cl_9] ~ (3-) is as follows: MoCl_2 ~ (2 +) and Mo_2Cl_9 ~ (3-) ) _2 (μ_2-Cl) _3Cl_6] ~ (11-), and then two S atoms replace the triple-bridged Cl atom. Molecular orbital calculations support the possible existence of intermediates (Mo_3Cl_ (11)) ~. The above addition process is also suitable for the formation of polynuclear ions Mo_4Cl_ (13) ~ + and Mo_6Cl_ (15) ~ (3 +).
