Oxamic acid acts as a bridging ligand with lanthanide ions to form, for example 9-coordinate Ho(III) systems in which the holmium centres are linked into sheets via H-bonds. Nd(III) also forms 9-coordinate complexes with oxamate but an alternative packing motif is observed. Multidentate ligands such as chloroanilate can also induce interesting networks. Thus with sodium and phenanthroline a complex which contains 7-coordinate sodium atoms linked together to form infinite double chains is observed.
