中文摘要:
      在CH3CH2OH/CH3OH溶剂中合成了标题配合物[Mn(H2O)6](C13H10NO4S)2{C13H10NO4S = 4-[ (2-羟基-亚苄基)-氨基]-苯磺酸阴离子},利用元素分析、红外光谱、X-射线单晶衍射和热分析等手段对配合物进行了表征.结果表明,该化合物属单斜晶系,空间群为P121/c1 , 其晶胞参数:a = 0. 633 48(2) nm, b = 3.564 08(8) nm, c = 0.944 25(3) nm, β = 131.790(2) ° , V = 1.589 53(8) nm3, Z = 2.在标题配合物中,Mn2+离子与6个配位水的6个氧原子配位形成畸变的八面体构型.脱质子的席夫碱并未参与配位,而是作为抗衡阴离子存在于配合物晶体结构中,从而使整个配合物呈电中性.
英文摘要:
      The complex [Mn(H2O)6] (C13H10NO4S)2 {C13H10NO4S = 4-[(2-Hydroxy- benzylidene)-amino]- benzenesulfonic acid anion } was prepared in the CH3CH2OH/CH3OH solution, and the complex was characterized by elemental analysis, IR spectra, X-ray diffraction and TG-DTG analysis. The results show that the compound belongs to monoclinic system with space group P121/c1and cell parameters are as follows: a = 0. 633 48(2) nm, b = 3.564 08(8) nm, c = 0.944 25(3) nm, β = 131.790(2) °, V = 1.589 53(8) nm3 , Z = 2.Mn(II) is coordinated by six O atoms from six coordination waters, forming a deformed octahedral geometry. The deprotonated Schiff base is not participated in coordination, but as counter anion in the crystal structure, which makes the whole complex electrically neutral.
