Öz

The formation of chelate compounds between dimedone-2-phenylazo and some tran- sition metal ions including Cu, Ni, Co, Zn and Mn was investigated spectrophotometrically, conductometrically and potentiometrically. Solid complexes were prepared, investigated by ir and analyscd for their elements. The results claimed to formation of a monoligated complex for the studied ions except in case of Co where a bilagated complex predominates. The stability constant were calculated and found to be in the order: Cu > Ni > Zn > Co > Mn
