Investigation into reaction of some metals with 2,2',4'-trioxyazobenzene substituted ones

The reaction of two 2, 2', 4'-trioxyazobenzene substituted ones with ions of copper (2), scandium (3), zirconium (4), vanadium (5), molybdenum (6) and palladium (2) is studied. Complexes of 5-sulfo- and 3-sulfo-5-nitro-2, 2', 4'-trioxyazobenzene with metals are tantomeric systems. The complex structure depends on the nature of metal. Main spectrophotometric characteristics of copper molybdenum, palladium scandium, zirconium and vanadium complexes are determined
