title: Structure, bonding, and fluorescence of bivalent metal chelates of o,o'-dihydroxyazobenzene.
abstract: The structure and bonding of bivalent metal chelates of o,o'-dihydroxyazobenzene (DHAB) have been studied by PMR and absorption spectroscopic methods. These studies indicate that fluorescence, which is observed only for the MgDHAB chelate, may arise from a greater degree of ionic character in the metal-oxygen bonds of this compound than in the other metal(II) chelates examined. Possible structures of these chelate compounds are proposed and discussed.
