On the basis of the results of first-principles band calculations, we report a strategy for the development of a conducting metalorganic framework (MOF). The charge carrier in a zirconium-based MOF, MIL-140A, is expected to be localized because of a mismatch of the energy levels of bridging ligands pi* and Zr 4d orbitals. On the basis of the findings, we propose a candidate structure for a conducting MOF.
