摘要
常温条件下在水和乙醇混合溶剂中,由苯并咪唑(BZM)、2,4,6-三甲基苯甲酸(HTMBA)与金属离子Co(Ⅱ)合成了1个新颖的三维超分子配合物[Co(BZM)2(TMBA)2]n,并通过X-射线单晶衍射、元素分析、红外光谱以及热稳定性分析等对其进行了结构测定和表征。分析表明,该配合物属正交晶系,Pbca空间群,中心金属离子Co(Ⅱ)是六配位,由4个氧原子和2个氮原子包围,氧原子分别来自2个2,4,6-三甲基苯甲酸分子,氮原子分别来自2个苯并咪唑分子。配合物通过范德华力形成3D网络结构。
At room temperature, a coordination polymer [Co(BZM)2 (TMBA)2]n. was synthesized by Co( Ⅱ ), benzimidazole (BZM) and 2,4,6-trimethyl benzoic acid (HTMBA) in CHaCHzOH/H,O solution and characterized by X-ray diffraction, cle- mental analysis, IR spectrum and thermogravimetric analysis. The study indicates that the complex was orrhorhombic crystal system and Pbca space group. The Co center is a hexa-coordination surrounded by two nitrogen atoms from two BZM molecules and four oxygen atoms from two HTMBA molecules. The complex is a 3D structure formed by Van Der Waals Force.
