制备了标题化合物单晶,确定了它的分子和晶体结构,结果表明Cu(II)与五个氧原子配位,其中之一来自沿轴向(CH3)2SO.形成略为变形的四方锥结构.在配体上的噻吩基取顺式围绕差Cu(II)原子,这可以共轭效应来解释.

The title compound, C18H14CuF6O5S3, is triclinic, space group P1, with a 9.440(3), b 10.497(2), c 11.907(2) ? a 82.58(2), b 84.02(2), and g 77.93(2)? d.(calcd.) = 1.709 for Z = 2. The Cu(II) atom is coordinated with 5 O atoms, 1 of which is from Me2SO, and forms a distorted square pyramid. The thienyl groups in the ligands are cis around the Cu(II) atom.

Key words: CRYSTAL STRUCTURE DETERMINATION, X-RAY DIFFRACTION ANALYSIS, COPPER COMPLEX, DMSO, BUTANEDIONE P, ORGANO FLUORINE COMPOUNDS, THIOPHENE P, LEAST SQUARE METHODS, BETA DIKETONES
