X-ray diffraction studies, electrical and optical properties of some metalcomplexes of the ligand including 1-amino-3-(N-benzylamino) propane

Metal complexes containing Cu+2, Ni+2 and Cd+2 of the ligand including 1-am ino-3-(N-benzylamino propane) named M2 - [CdL1](Cl-2), M3 - [CuL2](NO3)(2), M4 - [CuL2](Cl-2) and M5 - [NiL2](Cl-2) were investigated structurally by X-ray diffraction (XRD), electrically by two probe and optically by optical methods. From the XRD data, the unit cells of the samples were found as M2 , monoclinic, and M3, M4 and M5, triclinic. Hot probe and thermoelectric po wer measurements indicated that the complexes M2, M3, M4 and M5 have n-type of electrical conductivity and optical band gaps of the complexes are 1.66 , 1.31, 1.25 and 1.29 eV, respectively.
