Abstract: | Abstract The reaction of cobalt (II) chloride hexahydrate and N-tert-butyl-2-thioimidazole (tmt-Bu) yielded products k2-(tmt-Bu)2]CoCl2 (1) and (tmt-Bu)2Co2(μ-tmt-Bu)2Cl2]·CH3CN (2) at different reaction time. The single crystal X-ray diffraction analysis was carried out for 1 and 2 {Bruker Kappa Apex-II CCD diffractometer, MoKα radiation}. Crystal data for 1: orthorhombic P212121 unit cell a = 8.195(6) ?, b = 13.778(10) ?, c = 17.354(11) ? and V = 1960(2) ?3 whereas the compound 2 crystallizes in monoclinic system P21/c with unit cell a = 10.069(7) ?, b = 11.181(7) ?, c = 18.156 ?, β = 95.322(4)° and V = 2035.4(2) ?3. The complex 1 contains one dimensional chain running along the a-axis and the complex 2 contains one dimensional chain running along the b-axis due to existence of different types of intermolecular interaction. The change in structure of the product is directly
related to the reaction time i.e. reaction for lesser time produces mononuclear product and for longer time produces binuclear
compound. |
