The transparent colorless single crystal was obtained by reacting cadmium nitrate with phen and malonic acid (mal).The crystal structure was determined by X-ray diffraction.The crystal structure indicates that there are two compounds in one crystal cell and they are isomeric complexes with empirical formula C27H18O4N4Cd.They crystallize in triclinic system with space group P-1, a=0.14432(5) nm, b=0.15517(5) nm, c=0.16098(6) nm, α=107.048(6)°, β=98.989(6)°, γ=116.481(6)°, Z=2, F(000)=1287.Dc=1.453 g/cm3, μ=0.802 mm-1, R1 =0.0645, wR2=0.1756.Difference between the two isomeric complexes is that in complex 1 Cd2+ is coordinated by one oxygen atom of every carboxylate and in complex 2 Cd2+ is coordinated by two oxygen atoms in a carboxylate group.Two isomeric complexes formed supramolecular structure through hydrogen bonds and π-π stacking.

Key words: Cd(Ⅱ), mixed ligand complex, crystal structure, isomer, supermolecular
