[(n-C4H9)4N]2[Mo2O7]与浓盐酸在非质子溶剂中反应生成分子型氯化钼氧阴离子[Mo2O5Cl4]2−作为四正丁基铵盐。对[(n-C4H9)4N]2[Mo2O5Cl4]·1/3(C2H5)2O的x射线结构分析表明，二聚阴离子由两个moo3cl3八面体组成，具有较长的Mo-Mo距离（3.279 Å）。该化合物是迄今为止所分离的多核钼酸盐中酸度最高的化合物。
Reaction of [(n-C4H9)4N]2[Mo2O7] with concentrated hydrochloric acid in an aprotic solvent yields a molecular molybdenum oxychloride anion [Mo2O5Cl4]2−as a tetra-n-butylammonium salt. X-ray structural analysis of [(n-C4H9)4N]2[Mo2O5Cl4]·1/3(C2H5)2O revealed that the dimeric anion consists of two MoO3Cl3octahedra sharing a common face with a relatively long Mo–Mo distance (3.279 Å). The compound has the highest acidity as a polynuclear molybdate isolated so far.
