Single crystals of molybdenum(VI) tricopper(II) tellurium(IV) heptaoxide dichloride hemihydrate, MoCu3TeO7Cl2.0.5H2O, were synthesized via a transport reaction in sealed evacuated silica tubes. All atoms occupy general positions within the triclinic (P1) unit cell. The building units are irregular CuO4Cl and CuO3Cl2 square pyramids, distorted TeO3+1E trigonal bipyramids (E is the lone pair of TeIV) and irregular MoO5 pyramids. The TeO3+1E, CuO4Cl and CuO3Cl2 polyhedra form (110) layers bridged by Mo atoms. The water molecules are located in [100] channels.
通过在密封抽空的石英管中进行传输反应，合成了二氯化七氧化钼（VI）三铜（II）碲（IV）半水合物单晶，化学式为MoCu₃TeO₇Cl₂·0.5H₂O。所有原子占据三斜晶系（P1）晶胞内的一般位置。结构单元是不规则的CuO₄Cl和CuO₃Cl₂正方金字塔、扭曲的TeO₃ + 1E三角双锥体（E是Te⁴⁺的孤对电子）和不规则的MoO₅金字塔。TeO₃ + 1E、CuO₄Cl和CuO₃Cl₂多面体形成由Mo原子桥连的（110）层。水分子位于[100]通道中。
