1,3,5-Triazines. Part IX. Reactions of hexamethylmelamine with iodine

Abstract

Reactions of hexamethylmelamine with iodine in four solvents have been investigated. A 1:1 complex forms in n-hexane and carbon tetrachloride solutions and the association constants have been obtained by a spectrophotometric method. Polyiodide anions are produced in chloroform and methylene chloride solutions. A series of crystalline hexamethylmelaminium polyiodides, [N₃C₃(NMe₂)₃H]⁺ I_n^–(n= 1, 3, 5, or 9), has been prepared.
