Abstract: The coordinating behavior between 18 asymmetrical bisazo derivatives of chromotropic acid containing the auxochrome-COCH3, -NO2, -SO3H and rare earth elements has been investigated. The influences of the auxochrome-COCH3,-NO2,-SO3H and their substitutive position on the 'properties and the composition of the chelates have also been discussed.
