Abstract
Single crystals of Rb2[GeO2(OH)2] · 2H2O are studied by X-ray diffraction. The crystals belong to the orthorhombic system, sp. gr. Pna21, a = 13.523(6) Å, b = 8.143(4) Å, c = 13.407(6) Å, Z = 8, R 1 = 0.0506. In [GeO2(OH)2]2− anions, the Ge-O distances (1.71–1.73(1) Å) are shorter than the Ge-OH distances (1.76–1.80(1) Å). Anions are linked to each other by pairs of hydrogen bonds to form infinite chains. The chains are linked by hydrogen bonds involving water molecules to form a 3D structure. The assignment of the bands in the IR spectrum of the compound under study is performed.
