稳定的水溶性钽与乳酸的配合物（四乳酸二过氧-氧-双钽酸铵(V)）， （NH4）4[Ta2(C3H4O3)4(O2)2O]。3H2O，以结晶形式制备。根据单晶x射线衍射数据，该化合物形成一个单斜晶胞，a = 13.85(2) a, b = 9.06(1) a, c = 12.32(2) a, β = 116.30度，空间群C2（2号），每晶胞有Z = 2个分子。固体13C核磁共振数据和低高光参数与确定的结构一致。在拉曼光谱和红外光谱中出现相同的振动模式，支持了没有反演对称的空间群的选择。该钽配合物的溶液成功地用于合成NaTaO3和Sr2Ta2O7两种光催化材料。
The stable water-soluble tantalum complex with lactic acid (ammonium tetralactatodiperoxo-mu-oxo-ditantalate(V)), (NH4)4[Ta2(C3H4O3)4(O2)2O].3H2O, was prepared in the crystalline form. According to the single-crystal X-ray diffraction data, this compound forms a monoclinic cell with a = 13.85(2) A, b = 9.06(1) A, c = 12.32(2) A, and beta = 116.30 degrees , space group C2 (No. 2), and has Z = 2 molecules per unit cell. The solid-state 13C NMR data and low flack parameter are consistent with the determined structure. Appearance of the same vibration modes in Raman and IR spectra supports the choice of the space group without inversion symmetry. The solution of the tantalum complex was successfully applied for the synthesis of two photocatalytic materials, NaTaO3 and Sr2Ta2O7.
