• The structure of hydrated oxonium ion has been determined in a concentrated hydrochloric acid solution by the X-ray diffraction method. The oxonium ion H<SUB>3</SUB>O<SUP>+</SUP> combines with four water molecules to form a trigonal pyramid structure in which three water molecules have an H<SUB>3</SUB>O<SUP>+</SUP>–H<SUB>2</SUB>O distance of 2.44 Å, while the water molecule at the apex of the pyramid is separated by 2.90 Å from the central oxygen atom of the oxonium ion. The structure of the CoCl<SUP>+</SUP> determined in a relatively dilute lithium chloride solution (the Cl/Co mole ratio is 3.38) shows that the cobalt(II) ion is coordinated with five water molecules, the Co–OH<SUB>2</SUB> distance being 2.14 Å. The Co–Cl distance within the complex is 2.35 Å. The CoCl<SUB>4</SUB><SUP>2−</SUP> complex has a regular tetrahedral structure both in a concentrated lithium chloride (Cl/Co=22.1) and a hydrochloric acid (Cl/Co=21.1) solutions with the Co–Cl bond length of 2.29 Å.
