title: An M12(L(1))12(L(2))12 cantellated tetrahedron: a case study on mixed-ligand self-assembly.
abstract: In the self-assembly of Pd(II) ions and two different, but similarly shaped, ligands (1 and 2), neither random mixing nor self-sorting of the two ligands into two unmixed structures was observed. Instead a mixed, yet sorted, Pd12 (1)12 (2)12 cantellated tetrahedron (and its pseudoisomer) was selectively formed, thus revealing a fine example of intramolecular self-sorting. A case study showed that a homothetic ratio of >2 is necessary to observe cantellated tetrahedra.
