In[NC5H3(CO2)(2)](OH2)F: A new layered indium-organic framework material (NC5H3(CO2)(2)=2,6-pyridinedicarboxylate)

Abstract

A new layered indium-organic framework material, In[NC5H3(CO2)(2)](OH2)F has been synthesized by a hydrothermal reaction using In2O3, NH4F, 2,6-NC5H3(CO2H)(2) (2,6-pyridinedicarboxylic acid), HF, and water at 200 degrees C. Single-crystal X-ray diffraction was used to determine the structure of the reported material. In[NC5H3(CO2)(2)](OH2)F has a novel layered structure consisting of InO5NF polyhedra and the pyridinedicarboxylate organic linker. Detailed structural analyses with full characterization including infrared spectrum, thermogravimetric analysis, elemental analysis, exchange reactions for the coordinated water molecule, and gas adsorption experiments are reported.
