| NaGaSn, (trigonal; P3,12 (No. 151); a = 632.8(4), c = 617.0(3) pm, Z -1; d v = 5.33 g/cm 3) was grown from the melt. The crystal structure contains Ga and Sn atoms in a helical arrangement (six atoms per turn) along the c-axis direction. Interatomic bonding between neighbouring helices completes a distorted [2+2]-tetrahedral environment for every Ga/Sn position. The compound is classified in terms of the Zintl concept. | | | |

| The compound Sr 5 Al 2 Sb 6 crystallizes in the orthorhombic system (space group Pnma (No. 62)) with the lattice constants: a = 1212.4(4) pm, b = 1034.1(4) pm, c = 1340.9(5) pm. AlSb 4 tetrahedra are connected via common edges and corners to chains. Every second terminal Sb atom of the chain is connected to another Sb atom, such that end-on Sb 2 groups and terminal Sb alternate. The compound Ba 5 In 2 Sb 6 crystallizes in the orthorhombic system (space group Pbam (No. 55)). The lattice constants are: a = 1530.7(6) pm, b = 1335.8(5) pm, c = 478.6(2) pm. In the structure, InSb 4 tetrahedra are connected via common corners and Sb 2 groups to form double chains. Both compounds are classified as Zintl phases. | | | |

The crystal structures (Ibam, No. 72) are characterized by infinite chains o f edge sharing tetrahedra j, [MX4;,3'] (M = Al, In; X = P, As) which are isoelectronic to SiS2. The vibrational spectra can be interpreted with respect to the symmetry P(2/m 2/c) 42/ m -D 4h of the isolated polymeric chain ][M X 4(23"]. The assignment of the observed frequen cies is supported by a normal coordinate analysis using the fragment method. | | | |
