Materials Data on ZrMoP by Materials Project

ZrMoP crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Zr is bonded in a 11-coordinate geometry to six equivalent Mo and five P atoms. There are two shorter (2.96 Å) and four longer (3.01 Å) Zr–Mo bond lengths. There are four shorter (2.73 Å) and one longer (2.82 Å) Zr–P bond lengths. Mo is bonded in a 10-coordinate geometry to six equivalent Zr and four P atoms. There are two shorter (2.46 Å) and two longer (2.65 Å) Mo–P bond lengths. There are two inequivalent P sites. In the first P site, P is bonded in a 9-coordinate geometry to three equivalent Zr and six equivalent Mo atoms. In the second P site, P is bonded in a 9-coordinate geometry to six equivalent Zr and three equivalent Mo atoms.

Altering the solubility of metal–organic polyhedra via pendant functionalization of Cp 3 Zr 3 O(OH) 3 nodes

Here, the chemistry of zirconium-based metal-organic polyhedra (ZrMOPs) is often limited by their poor solubilities. Despite their attractive features—including high yielding and facile syntheses, predictable topologies, high stability, and tunability—problematic solubilities have caused ZrMOPs to be under-studied and under-applied. Although these cages have been synthesized with a wide variety of carboxylate-based bridging ligands, we explored a new method for ZrMOP functionalization via node-modification, which we hypothesized could influence solubility. Herein, we report ZrMOPs with benzyl-, vinylbenzyl-, and trifluoromethylbenzyl-pendant groups decorating cyclopentadienyl moieties. The series was characterized by 1 H/ 19 F NMR, high-resolution mass spectrometry, infrared spectroscopy, and single-crystal X-ray diffraction. The effects of node functionalities on ZrMOP solubility were quantified using inductively coupled plasma mass spectrometry. Substitution caused a decrease in water solubility, but for certain organic solvents, e.g. DMF, solubility could be enhanced by ~20×, from 16 μM for the unfunctionalized cage to 310 μM for the vinylbenzyl- and trifluoromethylbenzyl-cages.
