Synthesis and Self-Association of Organoplatinum(IV) Boronic Acids

Abstract

Oxidative addition of ortho,meta, and para isomers of BrCH2C6H4B(OH)2 to dimethylplatinum(II) complexes gave the corresponding organoplatinum(IV) boronic acids [PtBrMe2{CH2C6H4B(OH)2}(NN)], with the bidentate ligand NN = 4,4′-bis(ethoxycarbonyl)-2,2′-bipyridine or 2,5-bis(2-pyridyl)-1,3,4-oxadiazole. The complexes undergo self-assembly in the solid state through hydrogen bonding to give dimers, polymers, or sheet structures.
