Supramolecular assembly of anion-channel and anion-layer structures of [PtL4]X2 (L=nicotinamide; X=Cl or PF6): surprisingly robust arene ring ‘herringbone’ motifs and adaptable amide–amide hydrogen bonding
Abstract
Square-planar platinum cations PtL42+ (L=nicotinamide) form layer structures dominated by interdigitation of the ligands via ‘herringbone’ packing motifs; intercation amide–amide hydrogen bonding adapts to accommodate anion-channel or anion-layer structures.
