| Abstract: | The oxidative addition of compounds RBr to [PtMe2(bpox)], 1, bpox = 2,5-bis(2-pyridyl)-1,3,4-oxadiazole gave the corresponding organoplatinum(IV) complexes [PtBrMe2(R)(bpox)], 2, R = CH2CO2H; 3, R = CH2-4-C6H4CO2H; 4, R = CH2-4-C6H4CH2CO2H, whereas the reaction with BrCH2CH2CO2H gave only the platinum(II) complex [PtBrMe(bpox)], 5. The organoplatinum(IV) complexes with carboxylic acid substituents form unusual supramolecular structures in the solid state through hydrogen bonding interactions, some of which are supramolecular polymers. |
