•Synthesis of a novel diimine ligand.•Two diimine Cd(II) complexes have synthesized.•Crystal structure of Cd(II) complex has been investigated.
Two related diimine Cd(II) complexes, [CdLCl2] 1 and [CdLI2] 2, derived from ligand, (N1Z,N3Z)-N1,N3-bis(2-chlorobenzylidene)-2,2-dimethylpropane-1,3-diamine, L were reported. The synthesized and isolated ligand and its Cd(II) complexes were characterized by elemental analyses, IR, 1H- and 13C NMR and UV/Vis spectroscopy, ESI-MS spectrometry, and TGA/DTG studies. Both the complexes were synthesized under similar synthetic procedures and structure of complex 2 was additionally determined by single crystal X-ray diffraction studies. The diimine ligand was coordinated to Cd(II) ion through two nitrogen atoms, and possessed distorted tetrahedral geometry. TGA and DTG studies of the complexes were carried out at 20–800°C, and showed that the complexes were thermally stable and decomposed into three steps.
