The framework of the MOF with TNP in chloroform and the difference Fourier map. Electron densities in the solvent pore indicate the presence of TNP and/or solvent CHCl3 molecules near the framework. The two linkers connecting the same two metal ions are the statistically disordered H2dobdc ligands in the crystal structure
