studies and single-crystal X-ray diffraction. In complex 1, both the copper(II) atoms acquire a square-pyramidal coordination geometry. The distance between Cu1 and Cu2 atoms is 5.2541(8) A. The structure of complex 2 contains two bicopper(II) cations [Cu2(mapoa)(CH3OH)(bpy)2]2+, in which the Cu atoms acquire distorted square-pyramid coordination geometry (Cu1, Cu2, Cu4) or distorted trigonal bipyramid
摘要两种新的μ-草酰胺或μ-草酸酯桥联的双铜(II)配合物[Cu2(mapox)(bpy)2](ClO4)2(1)和Cu2(mapoa)(CH3OH)(bpy)2(pic)2 ·0.5H2O(2)(H2mapox = N,N'-双[3-(甲基氨基)丙基]-草酰胺,H2mapoa = N- [3-(甲基氨基)丙基]草酸酯,bpy = 2,2'-联吡啶,图片=苦味酸阴离子),已经通过元素分析,摩尔电导测量,光谱研究和单晶X射线衍射进行了合成和表征。在配合物1中,两个铜(II)原子都具有正方形-金字塔形的配位几何形状。Cu1和Cu2原子之间的距离为5.2541(8)A。配合物2的结构包含两个双铜(II)阳离子[Cu2(mapoa)(CH3OH)(bpy)2] 2+,其中Cu原子获得扭曲的正方形-金字塔配合几何(Cu1,Cu2,Cu4)或变形的三角双锥体配合几何(Cu3)。Cu⋯Cu的间距为5。2316(8)A(Cu1,Cu2)和5
