Resumen en inglés

An investigation of solid solutions of KHSeO4-KH2AsO4 has led to the discovery of a new compound, K2(HSeO4)1.5(H2AsO4)0.5 (dipotassium hydrogenselenate dihydrogenarsenate) (denoted KHSeAs). The crystals have been prepared at room temperature by slow evaporation of an aqueous solution containing K2CO3, H2SeO4 and H3AsO4. The compound was characterized by X-ray single-crystal analysis performed at room temperature and reveal that it crystallizes in the space group P1̄ with the following crystal data: a=7.4532(2) Å, b=7.7151(2) Å, c=7.7911(2) Å, α=71.8843(17) °, β=87.7804(16) ° and γ=86.0475(15) °...< Leer menos
