Polynuclear dicarboxylatotetrachromium (III) complexes are produced by reacting a dicarboxylic acid with a monobasic chromic (III) salt in a proportion of 4 moles of monobasic chromic (III) salt to 1 mole of dicarboxylic acid. Surface treating agents comprising these complexes provide a surface with desirable properties such as durable water repellency, adhesiveness, antistatic properties, etc.
