Complexes of 1,2-dipiperidinoethane with transition and representative metals

1,2-Dipiperidinoethane (DPE) reacts wit divalent first row transition and representative metals to give complexes of the stiochiometry. MLX2 when L=DPE, M=Cu(II), Ni(II), Co(II), Zn(II), Cd(II) and Hg(II)X = Cl-. Br-, I- and NO3-. The ligand and complexes have been characterized by elemental analysis, conductivity measurements, room temperature magnetic moment studies, proton NMR, electronic and IR spectra. The ligand in these complexes behaves as bidentate like substituted ethylenediamine coordinating through nitrogen atoms. The solid state IR study and other data support distorted tetrahedral geometry of the type MN2X2.
