标题化合物K2[TiO（C2O4）2]·2H2O的阴离子形成四个Ti和四个O原子的八元环。每个Ti原子处于畸变的八面体环境中。在具有反转中心的非平面环系统中，Ti和O之间的距离为1.789（3）至2.138（3）埃。K离子表现出八或十倍配位，典型的距离在2.649（17）和3.158（5）埃之间。一些钾离子和水分子是无序的。
The anions of the title compound, K2[TiO(C2O4)2].2H2O, form eight-membered rings of four Ti and four O atoms. Each Ti atom is in a distorted octahedral environment. Distances between Ti and O in the non-planar ring system, possessing an inversion centre, range from 1.789 (3) to 2.138 (3) angstrom. The K ions exhibit eight- or tenfold coordination with typical distances between 2.649 (17) and 3.158 (5) angstrom. Some of the K ions and the water molecules are disordered.
