The supramolecular chemistry of organoplatinum complexes containing amide or alcohol functional groups

The oxidative addition of alkyl bromides, RBr, to the dimethylplatinum(II) complex [PtMe2(bpox)], 1, bpox = 2,5-bis(2-pyridyl)-1,3,4-oxadiazole gave the corresponding organoplatinum(IV) complexes [PtBrMe2(R)(bpox)], R = CH2-4-C6H4C(=O)NHCH2Ph, 2; R = CH2-4-C6H4C(=O)NH-4-C6H4-t-Bu, 3; R = CH2-4-C6H4C(=O)NH-3,5-C6H3-t-Bu-2, 4; R = CH2-2-C6H4CH2OH, 5, which contain amide or alcohol functional groups. Several of these complexes form supramolecular polymers in the solid state through intermolecular hydrogen bonding. In complex 2 there is complementary hydrogen bonding between amide groups, while in complexes 3 and 5 the hydrogen bonding involves the oxygen atom of the bpox ligand as acceptor.
