Substituted pyrazole containing Schiff-base ligand, 5-methyl-3-formylpyrazole-N-(2′-methylphenoxy)methyleneimine, (MPzOA), afforded three new Cd(II) complexes, [Cd(MPzOA)Cl2]2.CH3OH (I), [Cd(MPzOA)2(H2O)2](ClO4)2 (II) and [Cd(MPzOA)(H2O)(NO3)2] (III). In the reported complex species the coordination number and geometry of Cd(II) vary. In complex I and II, Cd(II) adopts six and in (III) it adopts eight coordination modes, with prismatic, octahedral and distorted dodecahedral geometry, respectively. All the complexes are characterized by IR, 1H NMR, UV–Vis spectral parameters and X-ray analyses. The complexes have 1D, 2D and 3D supramolecular frameworks formed by non-covalent interactions, like hydrogen bonding, π … π stacking, C–H … π interactions.
A new pyrazole based Schiff-base ligand and its Cd(II) complexes have been synthesized & characterized. The structural conformations of the reported Cd(II) complexes have been established by X-ray studies and the emission properties metal ion complexes have been reported.Figure optionsDownload as PowerPoint slide
