The title hydrate, [Mo(2)Cl(2)O(5)(C(18)H(24)N(2))(2)]·0.2H(2)O, has been isolated as the oxidation product of [Mo(η(3)-C(3)H(5))Cl(CO)(2)(di-t-Bu-bipy)] (where di-t-Bu-bipy is 4,4'-di-tert-butyl-2,2'-bipyridine). A μ-oxide ligand bridges two similar MoCl(di-t-Bu-bipy)O(2) units, having the terminal oxide ligands mutually cis, and the chloride and μ-oxide trans to each other. In the binuclear complex, the coordination geometries of the metal atoms can be described as highly distorted octa-hedra. Individual complexes co-crystallize with a partially occupied water mol-ecule of crystallization (occupancy factor = 0.20; H atoms not located), with the crystal packing being mediated by the need to effectively fill the available space. A number of weak C-H⋯O and C-H⋯Cl inter-actions are present.
标题水合物[Mo₂Cl₂O₅(C₁₈H₂₄N₂)₂]·0.2H₂O是[Mo(η³-C₃H₅)Cl(CO)₂(di-t-Bu-bipy)](其中di-t-Bu-bipy为4,4'-二叔丁基-2,2'-联吡啶)的氧化产物。一个μ-氧配体桥连两个相似的MoCl(di-t-Bu-bipy)O₂单元,末端氧配体相互顺式排列,氯和μ-氧相互反式排列。在双核配合物中,金属原子的配位几何构型可描述为高度扭曲的八面体。单个配合物与一个部分占据的结晶水分子共结晶(占有率因子 = 0.20;氢原子未定位),晶体堆积是由有效填充可用空间的需要介导的。存在许多弱的C-H⋯O和C-H⋯Cl相互作用。
