Abstract
- PCM-101 is a phosphine coordination material comprised of tris(p-carboxylato)triphenylphosphine and secondary pillaring groups coordinated to [M <subscript>3</subscript> (OH)] <superscript>5+</superscript> nodes (M=Co, Ni). PCM-101 has a unique topology in which R <subscript>3</subscript> P: sites are arranged directly trans to one another, with a Pā ā ā P separation distance dictated by the pillars. Post-synthetic coordination of soft metals to the P: sites proceeds at room temperature to provide X-ray quality crystals that permit full structural resolution. Addition of AuCl groups forces a large distortion of the parent framework. In contrast, CuBr undergoes insertion directly between the trans-P sites to form dimers that mimic solution-phase complexes, but that are geometrically strained due to steric pressure exerted by the MOF scaffold. The metalated materials are active in heterogeneous hydroaddition catalysis under mild conditions, yielding different major products compared to their molecular counterparts.<br /> (© 2018 Wiley-VCH Verlag GmbH & Co.
