具有松散配位的三核钼簇合物[Mo_3(μ_3—S)(μ—S)_3(μ—dtp)(dtp)_3·(H_2O)](A)(dtp=S_2P(OC_2H_5)_2)和过量的咪唑反应时,(H_2O)配体和双啮桥基配体(dtp)可以同时被置换而形成标题化合物(Ⅰ)。晶体结构属三斜晶系,空间群P1。结构组成包括簇阳离子[Mo_3(μ_3—S)(μ—S)_3(dtp)_3·(C_3H_4N_2)_3],(dtp)阴离子及丙酮溶剂。簇阳离子具有近似C_3对称性,三个Mo原子基本上形成等边三角形,其Mo—Mo键长分别为2.763(1),2.762(1),和2.756(1),此簇合物是配体取代反应系列研究的产物之一,是由已知原子簇反应获得新型簇合物的一个例证。
The three-core molybdenum clusters [Mo_3 (μ_3-S) (μ_S) _3 (μ-dtp) (dtp) _3 · (H_2O)] (A) (dtp = S_2P (OC_2H_5) _2) With an excess of imidazole, the (H 2 O) ligand and the double-bridged ligand (dtp) can be replaced simultaneously to form the title compound (I). Crystal structure is triclinic, space group P1. Its structure includes cluster cations [Mo_3 (μ_3-S) (μs) _3 (dtp) _3 · (C_3H_4N_2) __3], (dtp) anions and acetone solvents. The cluster cations have an approximately C_3 symmetry and the three Mo atoms form an equilateral triangle with Mo-Mo bond lengths of 2.763 (1), 2.762 (1) and 2.756 (1), respectively. This cluster is a ligand One of the products substituted for the series of reactions is an example of a novel cluster obtained from a known cluster reaction.
