【摘要】 合成了5-硝基间苯二甲酸锰的配合物———Mn(nip)(H2O)5,并用X射线单晶衍射、元素分析、DSC、TG和DTG技术对其进行了表征。配合物的配位中心Mn(Ⅱ)与5-硝基间苯二甲酸和5个水分子配位形成配位八面体结构。根据热分析结果和FT-IR分析可推断,加热过程中该晶体先失去5个配位水,后失去配体5-硝基间苯二甲酸,同时生成氧化锰和某种聚合物。更多还原

【Abstract】 The crystal of the title complex Mn（nip）（H₂O）₅（nip=5-nitroisophthalate） was synthesized,and cultured in the filtrate of the reaction mixture.The X-ray single crystal diffractometer with graphite monochromated（MoK_α（λ= 0.71073 ））,elemental microanalysis,FT-IR,DSC and TG-DTG techniques were used to characterize the structure and thermal behaviors of the title complex.The results show that the central Mn²⁺ cation coordinates to the ligands（5-nitroisophthalate） and 5H₂O in a distorted octahedral pattern.And the title coordination compound loses its five water molecules at the first step and the 5-nitroisophthalate at the second step during heating based on the thermal analyses and FT-IR data.更多还原
