Abstract
Complex formation of tetraphenylarsonium bromide with molecular iodine in a chloroform solution was studied. Spectrophotometry with the use of the medium iodine number function was used to estimate the limiting number of iodine molecule coordinated with the bromide ion in the solution and the stability complex of the complex. According to X-ray diffraction data, the cation and anion of [(C6H5)4As]+I2Br− in crystal reside in a special position on the C 2 axis, and a superposition of the I −3 and Br2I− anions is observed, with ratios of 0.526 and 0.474, respectively. The resulting salt is isostructural to reported tetraphenylphosphonium interhalides.
