Dichloro(4,4'-dialkyl-2,2'-bipyridine-kappa2N,N')platinum(II), where alkyl is pentyl and heptyl.
Dichloro(4,4'-dipentyl-2,2'-bipyridine-kappa2N,N')platinum(II), [PtCl2(C20H28N2)], adopts a discrete pi-pi stacking structure, where the alkyl chains are located in a random manner. In contrast, dichloro(4,4'-diheptyl-2,2'-bipyridine-kappa2N,N')platinum(II), [PtCl2(C24H36N2)], forms a layer structure comprised of alkyl chain layers and paired coordination sites, as observed for analogous complexes with longer alkyl chains.
