A non-interpenetrating 3D porous metal-organic framework (MOF) holding rutile-type topology containing Cu4 secondary building units

摘要

In this work, we obtained a rarely three-dimensional porous Cu(II) MOF, namely [Cu2(BTC)(OH)(Me2NH) · 2H2O· DMF]_n (Me2NH-dimethylamine, [BTC~(3-)-1,3,5-benzenetricarboxylate, DMF-N,N'-dimethylformamide], by solvo(hydro)themial method. This polymer was characterized by single-crystal X-ray diffraction, EA, and ther-mogravimetry analysis. The outstanding structural feature of it is the coordination of Me2NH-a hydrolysate from DMF, and the non-interpenetrating porous rutile net Further, based on the investigation of literatures, we also discussed the architectonics involving common Cu4 secondary building unit (SBU) in detail.
