The structure-directing effect of guest binding in metallo-supramolecular assemblies of host-type ligands is observed with a 2-D coordination polymer formed between Cd(OAc)2 and tris(4-pyridylmethylamino)cyclotriguaiacylene in the presence of the globular guest o-carborane, and a trinuclear Cd(II) complex formed in solution in the absence of the bulky guest.
