The incorporation of kinetically inert metal ions as structural elements in crystalline coordination polymers is a synthetic challenge. While a small family of materials based on inert ions has been prepared (<i>i.e.</i> Cr(III)-based MIL-100, MIL-101, and [Ru<sub>6</sub>(btc)<sub>4</sub>Cl<sub>3</sub>]), general strategies that enable reticular synthesis have not been reported. Here we describe the mechanochemical synthesis of a reticular family of crystalline Ru<sub>2</sub>[II,III]-based materials by polymerization of molecular Ru<sub>2</sub> complexes, featuring unprotected carboxylic acid substituents, with Cu(OAc)<sub>2</sub>. The resulting crystalline heterobimetallic MOFs are solid-solutions of Ru<sub>2</sub> and Cu<sub>2</sub> sites housed within [M<sub>3</sub>L<sub>2</sub>] phases. The developed mechanochemical strategy is modular and allows for control of the primary coordination sphere of the Ru<sub>2</sub> sites. We anticipate the strategy will provide a rational approach to incorporation of kinetically inert ions in porous crystalline coordination networks, generating a class of atomically precise mixed-metal materials.

Eight mixed-ligand coordination networks, [Cd(2-aba)(NO3)(4-bphz)3/2]n·n(dmf) (1), [Cd(2-aba)2(4-bphz)]n·0.75n(dmf) (2), [Cd(seb)(4-bphz)]n·n(H2O) (3), [Cd(seb)(4-bpmhz)]n·n(H2O) (4), [Cd(hpa)(3-bphz)]n (5), [Zn(1,3-bdc)(3-bpmhz)]n·n(MeOH) (6), [Cd(1,3-bdc)(3-bpmhz)]n ·0.5n(H2O)·0.5n(EtOH) (7), and [Cd(NO3)2(3-bphz)(bpe)]n·n(3-bphz) (8) were obtained by interplay of cadmium nitrate tetrahydrate or zinc nitrate hexahydrate with 2-aminobenzenecarboxylic acid (H(2-aba)), three dicarboxylic acids, sebacic (decanedioic acid, H2seb), homophthalic (2-(carboxymethyl)benzoic acid, H2hpa), isophthalic (1,3-benzenedicarboxylic acid, H2(1,3-bdc)) acids, bis(4-pyridyl)ethane (bpe) and with four azine ligands, 1,2-bis(pyridin-4-ylmethylene)hydrazine (4-bphz), 1,2-bis(1-(pyridin-4-yl)ethylidene) hydrazine (4-bpmhz), 1,2-bis(pyridin-3-ylmethylene)hydrazine (3-bphz), and 1,2-bis(1-(pyridin-3-yl) ethylidene)hydrazine (3-bpmhz). Compounds 1 and 2 are 1D coordination polymers, while compounds 3–8 are 2D coordination polymers. All compounds were characterized by spectroscopic and X-ray diffraction methods of analysis. The solvent uptakes and stabilities to the guest evacuation were studied and compared for 1D and 2D coordination networks. The de-solvated forms revealed a significant increase of emission in comparison with the as-synthesized crystals.
