Supramolecular organoplatinum(iv) chemistry: a nanotube structure supported by hydrogen bonds.
The oxidative addition of 4-BrCH(2)C(6)H(4)-C(=O)NH-t-Bu to [PtMe(2)(bu(2)bipy)], bu(2)bipy = 4,4'-di-tert-butyl-2,2'-bipyridine, gave [PtBrMe(2)(CH(2)C(6)H(4)-C(=O)NH-t-Bu)(bu(2)bipy)], which reacted with AgX and a bridging ligand LL to give binuclear complexes [{PtMe(2)(CH(2)C(6)H(4)-C(=O)NH-t-Bu)(bu(2)bipy)}(2)(mu-LL)]X(2), LL = 1,4-pyrazine or 4,4'-bipyridine, X = BF(4) or PF(6). The complexes all take part in hydrogen bonding through either NHO[double bond]C, NHFB or NHFP interactions and, in the case with LL = 4,4'-bipyridine, X = PF(6), a supramolecular structure containing tubes is formed.
