Crystal and Molecular Structure of Diphenyliodonium Diiodobromide

摘要

A new salt, diphenyliodonium diiodobromide [C_(12)H_(10)I~+][BrI2~-], was synthesized, isolated as brown crystals, and studied by XRD. The structure of the diphenyliodonium diiodobromide consists of separate, nearly linear anions Brl2~-, and cations C_(12)H_(10)I~+. In the crystal of the salt there are strong intermolecular anion-anion (BrI2~-···I2Br~-) and anion-cation (I2Br~···I~+) interactions. The complexation in the system of organic cation bromide-elemental iodine was studied spectrophotometrically.
