摘要:

本文利用均苯三甲酸作为T型基块,先通过其与过渡金属锰离子配位构筑了一个双重层状框架,再通过氢键和π-π堆积相互作用构筑了一个三维的金属-有机配位聚合物Mn3(BTC)2(H2O)9·(H2O)(H3BTC=均苯三甲酸),并通过元素分析,ICP,TG,IR和X射线单晶衍射分析等手段对其结构进行了表征.

Abstract:

A new metal-organic polymer Mn3(BTC)2(H2O)9·(H2O) was synthesized by reaction of the metal ions Mn(Ⅱ) with 1,3,5-benzenetricarboxylic acid(H3BTC) in a mixed solution of DMF/C2H5OH/H2O and crystallized. The crystal belongs to monoclinic system,space group C2/c with a=1.901 4(4) nm,b=0.740 23(15) nm,c=2.044 9(4) nm,β=97.18(3)°,V=2.855 5(10) nm3,Z=4,Dc=1.766 g/cm3,μ(Mo Kα)=1.401 mm-1,R[I>2σ(I)]=0.072 7,wR=0.235 1 for 2 419 independent reflections with goodness-of-fit 1.046. Its structure possesses bilayer architectures constructed from Mn ions linked infinite Mn(BTC) chains which were build up from BTC ligand as the “T-shape” module and Mn as the linear module.The hydrogen-bond and π-π stacking interactions between bilayers make them three-dimensional channel-like interpenetrated frameworks.

Key words: Metal-organic polymer; Crystal structure; “T-shape” module, Metal-organic polymer, Crystal structure, "T-shape", module
