In the title compound, KGd(C(10)H(2)O(8))(H(2)O)(2), the Gd(3+) ion is nine-coordinated by eight O atoms from five individual benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligands and one water mol-ecule, and the K(+) ion is eight-coordinated by six O atoms from five individual btec ligands and two water mol-ecules. In the crystal, the btec half-mol-ecules are completed by crystallographic inversion symmetry. GdO(9) and KO(8) polyhedra are connected, forming layers in the ab plane, which are further inter-connected by μ(8)- or μ(12)-bridging btec ligands, forming a three-dimensional structure.
在标题化合物[KGd(C₁₀H₂O₈)(H₂O)₂]ₙ中，Gd³⁺离子由来自五个独立的苯-1,2,4,5-四羧酸根（btec）配体的八个O原子和一个水分子九配位，K⁺离子由来自五个独立的btec配体的六个O原子和两个水分子八配位。在晶体中，btec半分子通过晶体学反演对称性完成。GdO₉和KO₈多面体相连，在ab平面形成层，这些层通过μ(8)-或μ(12)-桥连的btec配体进一步相互连接，形成三维结构。
