Synthesis and Characterization of a New Ligand 2-(4,5-Dihydro-2-thiazolyl)-6-methoxylbenzothiazole and Its Dinuclear Co(Ⅱ)Complex

摘要

A new ligand 2-(4,5-dihydro-2-thiazolyl)-6-methoxyl benzothiazole and its new dinuclear Co(II) coordination complex [Co(C11H10N2OS2)Cl2]2·2CHCl3 (1) have been synthesized and characterized. Complex 1 was synthesized by the reaction of Co(II) salt with 2-(4,5-dihydro- 2-thiazolyl)-6-methoxyl benzothiazole under room-temperature evaporation condition and struc- turally characterized by single-crystal X-ray diffraction analysis and IR spectroscopy. The supramolecular network of complex 1 is stabilized by the presence of intermolecular interaction, such as C–H···Cl hydrogen bonding and π-π stacking. The complex crystallizes in triclinic, space group P1 with a = 8.3288(12), b = 10.5273(15), c = 10.822(2), α = 93.416(3), β = 90.864(3), γ = 94.890(3)o, V = 943.60(2)3, Z = 2, Dc = 1.758 g/cm3, F(000) = 498 and μ = 1.840 mm-1. The final complex [Co(C11H10N2OS2)Cl2]2·2CHCl3 is a diplex bridged dinuclear complex consisting of two Co(II) ions, two ligands, two bridging Cl- anions and two terminal Cl- anions.
