Implementation of the Hard-Soft Acid-Base Principle for the Direct Synthesis of Bimetallic Zirconium-Nickel and Hafnium-Nickel Metal-Organic Frameworks with a Polar Pore Environment.

ABSTRACT: An important direction in MOFs is the development of materials with well-defined and ordered heterogeneity toward novel functionalities and control of important properties at the atomic scale. A great approach is the designed synthesis of mixed-metal MOFs (M'MOFs) made of different building units based on distinct metal cations. However, their in-situ formation and co-assembly into an extended crystalline framework present great challenges due to the different kinetic and thermodynamic parameters. We report the successful synthesis of two isostructural, bimetallic Zr-Ni and Hf-Ni M'MOFs following the hard and soft acid and base (HSAB) principle. Single-crystal X-ray diffraction analysis revealed the formation of a 3D structure that features an in-situ formed [Ni(HPyC)₄Cl_2</
