title: The antimony-based type I clathrate compounds Cs(8)Cd(18)Sb(28) and Cs(8)Zn(18)Sb(28).
abstract: In phase: The title compounds lie in a new region of phase space for such a structure, and have stoichiometries in accord with a classical Zintl phase formulation. The small semiconductor gaps indicated by DFT calculations are also supported by their diamagnetic susceptibilities.
