Abstract

The binary germanides M12Ge17 and M4Ge9 (M = Na, K, Rb, Cs) and the stannides M12Sn17 and M4Sn9 (M = K, Rb, Cs) were identified by a combination of direct synthesis, thermogravimetric analysis, Vibrational spectroscopy, X-ray powder data and single crystal structure analysis. The M12E17 phases contain the cluster anions [E-9](4-) and [E-4](4-) in the ratio 1:2, forming a hierarchical structure with the cluster anions at the atomic positions of the hexagonal Laves phase MgZn2. Like the M4E4 phases, the M4Ge9 compounds are hierarchical derivatives of the cubic Cr3Si structure but with [Ge-9](4-) anions. The thermogravimetric analyses give strong evidence for the existence of at least one more phase with [E-9](4-) and [E-4](4-) clusters and of the clathrate phases M6E25 and MxE136 in addition to the well-known M(8)E(44)square(2) chlathrates.
