Estimation of conventional C-H∙∙∙π (arene), unconventional C-H∙∙∙π (chelate) and C-H∙∙∙π (thiocyanate) interactions in hetero-nuclear nickel-cadmium complexes with a compartmental Schiff base: Novel example of a diamine bridged hetero-polynuclear complex having NiO2Cd core

Abstract

Three new heteronuclear nickel(II)/cadmium(II) complexes, [(SCN)(Cl)Cd(L)Ni(DMF)2] (1), [(SCN)(CH3CO2)Cd(L)Ni(CH3OH)2] (2) and [(SCN)(Cl)Cd(L)Ni(NH2CH2CH2CH2NH2)]n (3) {where H2L = N,N'-bis(3-ethoxysalicylidene) propane-1,3-diamine is a potential hexadentate compartmental Schiff base}, have been synthesized and characterized by elemental analysis, IR, UV-Vis and fluorescence spectroscopy. The structures of the complexes have been confirmed by single crystal X-ray diffraction studies. In each complex, nickel(II) is placed in the inner N2O2 environment and cadmium(II) is placed in the outer O4 compartment of the compartmental Schiff base. Furthermore, the importance of unconventional C-H∙∙∙π (chelate) interactions in the solid state of complexes 1 and 2 have been described by means of DFT and MEP calculations and characterized using the NCI plot. All complexes show photoluminescence at room temperature upon the irradiation of ultraviolet light. The life times of excited states are in the range of 2-6 ns.
