Abstract The reaction of copper(II) acetate with ethyl(2-benzothiazolyl)aminoformate (HL) gave red crystals of [Cu2L4]2 (1). When complex 1 was treated with pyridine (Py) in chloroform/toluene, red crystals of CuL2(Py)2 (2), were deposited. Both complexes have been characterized by single-crystal X-ray diffraction methods, showing that the binuclear complex 1 has the copper atoms each located in a four-coordinate
摘要乙酸铜(II)与(2-苯并噻唑基)氨基甲酸乙酯(HL)反应生成[Cu2L4] 2(1)的红色晶体。用吡啶(Py)在氯仿/甲苯中处理配合物1时,沉积了红色结晶CuL2(Py)2(2)。两种配合物均已通过单晶X射线衍射法表征,表明双核配合物1的铜原子均位于N4的四坐标方平面几何结构中,两个独立的分子处于不对称单元中。CuN(胺)和CuN(bta)(bta =苯并噻唑基)的平均键距分别为1.98和2.07A。络合物2为单核,且Cu原子也在正方形平面中。CuN(py)和CuN(amine)的键距分别为2.011(4)和1.997(4)A。
