摘要
该文采用溶剂挥发法得到两个过渡金属配合物苯磺酸锌[Zn(H2O)6](C6H5SO3)2(1)和对甲基苯磺酸锌[Zn(H2O)6](p-CH3C6H4SO3)2(2),均为无色块状晶体。采用红外光谱、核磁共振光谱、热重分析和X-射线单晶衍射法对两个配合物的结构进行了表征。结果表明,两个配合物均为单斜晶系,P21/c空间群,配合物中Zn(Ⅱ)离子均与6个配位水分子中的氧原子配位,形成畸形的八面体空间构型,再通过氢键和π-π堆积作用形成三维超分子结构。还研究了两个配合物的固体荧光性能。
Two transition metal complexes including zinc benzenesulfonate[Zn(H2O)6](C6H5SO3)2(1)and zinc p-tolylsulfonate[Zn(H2O)6](p-CH3C6H4SO3)2(2)are obtained by the slow evaporation method in water,and the two products are all the colorless block crystal.The structures of the two complexes are characterized by infraved radiation(IR),nudear magnetic resonance(NMR),thermal gravimetric analysis(TGA)and X-ray single crystal diffraction.The results show that the two complexes belong to the monoclinic system and the space group P21/c.The Zn(Ⅱ)ions in the two complexes all coordinate with the oxygen atoms in the six coordination water molecules to form a deformed octahedral spatial configuration.They extend to a three-dimensional supramolecular structure through hydrogen bonds andπ-πinteractions.In addition,the solid-state fluorescent properties of two complexes are studied.
