Abstract: | The structural effects of incorporating a non-planar neutral metal complex, bis(2-guanidinobenzimidazolo)nickel(II), into three supramolecular arrays are described. The complex has a donor-acceptor-donor (DAD) hydrogen bonding motif on each ligand and this motif is used to link it to bis(biureto)nickelate(II) ions, or to 1,8-naphthalimide or phthalimide molecules, all of which incorporate a complementary acceptor-donor-acceptor (ADA) hydrogen bonding motif. The geometry about the metal ion as well as the nature of the network of hydrogen bonds formed have significant influences on the supramolecular structure adopted. An interesting combination of intramolecular hydrogen bonding and close ~ -stacking interactions also occur in each species. |
