Basic copper(ii) dihydroxoborate Cu2{BO(OH)2}(OH)3 contains infinite chains consisting of [CuO4] squares that are linked together by sharing opposite edges, due to which this compound is interesting in terms of low-dimensional magnetism. However, investigations of its physical properties are hindered by difficulties with the preparation of single-phase samples. The synthesis method was optimized, and the factors affecting the formation of a crystalline product were established. The synthesized compound was characterized by X-ray diffraction and IR spectroscopy, and its thermal stability was studied. The crystallite formation from the initially unstructured precipitate is described using scanning electron microscopy. An investigation of the temperature dependence of magnetic susceptibility showed that the magnetic properties of basic copper(ii) borate are well described by the weakly alternating spin-1/2 Heisenberg chain model.
