Abstract

Abstract We present a highly unusual example of self-assembly, specifically a polar, mixed- ligand cage which forms in preference to symmetrical homo-ligand products, and which suggests that steric effects can be exploited to obtain novel non-uniform polyhedral cages. In particular, reaction between the bulky tripodal triphosphine 2, 4, 6-tris (diphenylphosphino) triazine, L1, the non-bulky tripodal trinitrile 2, 4, 6-tris (cyanomethyl) trimethylbenzene, L2 ...
