报道了4-乙酰基-N-[(环己基氨基)羰基]苯磺酰胺(acetohexamide)与吡啶的铜(II)配合物的制备、光谱性质和晶体结构。合成了Cu(AH)_2(py)_2(AH =乙酰己脲,py =吡啶)配合物,并通过X射线衍射和电子自旋共振(ESR)对其进行了表征。配合物属单斜晶系,P21/a空间群,a = 17.412(6),B= 9.039(2),c= 26.531(10)°,β = 102.24(2)°,Z = 4。最终的细化使用3892个独特的反射,并给出0.0646的R值。铜原子被四个氮原子以正方形平面排列包围,两个来自乙酰己酰胺配体(Cu <$N = 2.009 <$),两个来自吡啶分子(Cu <$N = 2.016 <$),呈反式几何构型。ESR数据支持铜与dx 2 − y2轨道上的未成对电子有类似的配位行为(g> g>ge)。
The preparation, spectral properties, and crystal structure of a copper(II) complex of 4-acetyl-N-[(cyclohexylamino)carbonyl]benzenesulfonamide, which is known as acetohexamide, and pyridine are reported. The complex Cu(AH)2(py)2, where AH = acetohexamide and py = pyridine, was prepared and characterized by X-ray and ESR. The complex is monoclinic, space groupP21/a, witha= 17.412(6),b= 9.039(2),c= 26.531(10) Å , β = 102.24(2)°, andZ= 4. The final refinement used 3892 unique reflections and gave anRvalue of 0.0646. The copper atom is surrounded by four nitrogen atoms in a square-planar arrangement, two from the acetohexamide ligands (CuN = 2.009 Å) and two from the pyridine molecules (CuN = 2.016 Å) in a trans geometry. The ESR data support a similar coordination behavior of the copper (g∥>g⊥>ge) with the unpaired electron in the dx2−y2orbital.
