    Description / Table of Contents: Kristallstruktur von Bi14I4. Kondensierte Bismut-ClusterDie Kristallstruktur von Bi14I4  -  des Endgliedes der bekannten Bismuthalogenide  -  wurde mit röntgenographischen Methoden bestimmt (Einkristall, P21/m, Z = 1, a = 13,309(3) å, b = 11,447 (3) å, c = 4,342 (1) å, γ = 92,08 (3)°, R/Rw = 0,060/0,060 für 369 Reflexe, sinθ/λ ≤ 0,593, MoKα). Die Struktur besteht aus kondensierten Bismut-Clustern und ist aus unendlichen, eindimensionalen Bismut-Netzen aufgebaut, die sich entlang der c-Achse erstrecken und an den Enden Iodatome tragen.Die Besonderheiten der Bismutsubhalogenide, die auch kondensierte Cluster enthalten, werden in bezug auf Bindungslängen und Bindungswinkel besprochen. Die Einwirkung des einsamen Elektronenpaares des Bismutatoms auf die Gestalt der Koordinationspolyeder wird ebenso diskutiert wie der Zusammenhang zwischen der Koordination und der Oxidationsstufe der Bi-Atome.
    Notes: The crystal structure of Bi14I4  -  the final known member of binary bismuth halides  -  was determined by the single crystal X-ray diffractometer technique (P21/m, Z = 1, a = 13.309(3) Å, b = 11.447 (3) å, c = 4.342(1) å, γ = 92.08(3)°, R/Rw = 0.060/0.060 for 369 reflections, sinθ/λ≤ 0.593, MoKγ). The structure consists of condensed bismuth clusters and is build up from infinite one-dimensional bismuth nets running along the c-axis and limited by iodine atoms in another direction.The common structural features of bismuth subhalides containing condensed clusters are also considered based on the analysis of interatomic distances and bond angles. The influence of the lone pair of electrons of the bismuth atom on the geometry of bismuth coordination polyhedra, and the connection between bismuth atoms coordination and the formal oxidation state of these atoms is discussed.

    Description / Table of Contents: Synthese und Kristallstruktur von Hg5Sb2I6Das Antimonid-Iodid von Quecksilber, Hg5Sb2I6, früher irrtümlich als Hg3Sb2I4 formuliert, wurde in Standardampullen synthetisiert. Einkristalle wurden mittels Transport über die Gasphase erhalten. Hg5Sb2I6: Raumgruppe Pc21n, Gitterparameter: a = 8,108(1), b = 10,702(1), c = 21,295(1) Å. Die Struktur (Einkristall) ist aus [HgSbI3]-Tetraedern und [HgSbI2]-Dreiecken aufgebaut. Alle Antimonatome sind paarweise zu Sb24--Hanteln verbunden. Die Struktur wird mit anderen Strukturen, die Sb24--Hanteln enthalten, verglichen.
    Notes: Mercury antimonide iodide, Hg5Sb2I6, previously and erroneously reported as Hg3Sb2I4 was synthesized using standard ampoule technique. A gas-phase transport reaction was applied for preparation of single crystals. Hg5Sb2I6 crystallizes in the space group Pc21n (No. 33) with unit cell dimensions: a = 8.108(1), b = 10.702(1), c = 21.295(1) Å. Crystal structure solved using single crystal X-ray data is built of [HgSbI3] tetrahedra and [HgSbI2] triangles. All antimony atoms are joined into Sb24- dumbbells. The structure is compared with ones containing similar Sb24- dumbbells.
