초록
A series of reactions between an amino alcoholic ligand, cis-2-((2-((2-hydroxyethyl)amino)ethyl)amino)cyclohexan- 1-ol (HEAC), with the mixtures of group 12 metals including, HgCl2/CdCl2, HgCl2/CdI2, ZnCl2/CdCl2 and ZnCl2/ CdCl2/HgCl2 was experimentally and theoretically studied to determine the most stable product of these reactions. Furthermore, the Cambridge Structural Database (CSD) studies were done to evaluate the theoretical results. The products were characterized by elemental analysis, FT-IR, Raman, 1H NMR spectroscopy and single-crystal X-ray diffraction. Based on these investigations a binuclear structure of cadmium, [Cd2(HEAC)2(μ-Cl)2Cl2] (1), is the most stable product that was formed in all studied reactions between HEAC and metals mixtures. In this structure, the cadmium atom has a CdN2O(μ-Cl)2Cl environment and distorted octahedral geometry.
Abstract
A series of reactions between an amino alcoholic ligand, cis-2-((2-((2-hydroxyethyl)amino)ethyl)amino)cyclohexan- 1-ol (HEAC), with the mixtures of group 12 metals including, HgCl2/CdCl2, HgCl2/CdI2, ZnCl2/CdCl2 and ZnCl2/ CdCl2/HgCl2 was experimentally and theoretically studied to determine the most stable product of these reactions. Furthermore, the Cambridge Structural Database (CSD) studies were done to evaluate the theoretical results. The products were characterized by elemental analysis, FT-IR, Raman, 1H NMR spectroscopy and single-crystal X-ray diffraction. Based on these investigations a binuclear structure of cadmium, [Cd2(HEAC)2(μ-Cl)2Cl2] (1), is the most stable product that was formed in all studied reactions between HEAC and metals mixtures. In this structure, the cadmium atom has a CdN2O(μ-Cl)2Cl environment and distorted octahedral geometry.
