Hydrothermal treatment of indium(III) nitrate with a flexible pseudo C (3)-symmetric tricarboxylic acid at 115(a similar to)C for 5 days in DMF yields a new layered anionic indium carboxylate framework, [(CH3)(2) NH (2))][In(L)(HCOO)(DMF)] (n) (1) (L = 2,4,6-tris[(4(')-carboxyphenoxy)methyl]-1,3,5-trimethylbenzene), existing as two-dimensional sheets. The framework solid has been characterized by elemental analysis, FT-IR spectroscopy, TGA, PXRD and single crystal X-ray diffraction studies. DMF undergoes cleavage to dimethyl ammonium and formate ions, which are incorporated in the framework. A slipped stacking of the two dimensional sheets along a-axis in 1 results in a drastic decrease in the anticipated large porosity of the framework.
