Abstract

Selective adsorption of the CO₂ in environment is an important research field of inorganic chemistry and coordination chemistry. A coordination polymer [Co₂(tib)₂(1,4-NDC)₂]·7H₂O (CTN) was composed by the reaction of 1,3,5-tris(1-imidazolyl) benzene (tib) and 1,4-naphthalenedicarboxylic acid (1,4-H₂NDC) with Co²⁺ under solvothermal conditions. The result of X-ray single-crystal analysis shows that CTN is a twofold interpenetrating 3D framework with {4²·6⁵·8³}{4²·6} topology. CTN was further characterized by powder X-ray diffraction, IR spectroscopy, thermogravimetric analysis, and elemental analysis. Notably, CTN possesses an excellent CO₂ absorption property.

摘要

环境中CO _{2 的}选择性吸附是无机化学和配位化学的一个重要研究领域。配位聚合物[Co ₂ (tib) ₂ (1,4-NDC) ₂ ]·7H ₂ O (CTN)由1,3,5-三(1-咪唑基)苯(tib)和1 ,4-萘二甲酸 (1,4-H ₂ NDC) 与 Co ²⁺在溶剂热条件下。X射线单晶分析结果表明，CTN是一个具有{4 ² ·6 ⁵ ·8 ³ }{4 ²·6}拓扑。CTN 通过粉末 X 射线衍射、红外光谱、热重分析和元素分析进一步表征。值得注意的是，CTN具有优异的CO ₂吸收性能。
