    Description / Table of Contents: Die Verfeinerung der Kristallstruktur des Sr3Hg2Aus Mischungen von Strontium und Quecksilber im Molverhältnis 7:3 kann man durch Tempern bei 520°C (20 Tage) phasenreine Proben von Sr3Hg2 erhalten, aus denen Einkristalle ausgelesen werden können. Sr3Hg2 kristallisiert im U3Si2-Typ (Raumgruppe P4/mbm) mit a = 8,883(2) Å und c = 4,553(1) Å. Alle Hg-Atome sind in Hanteln eingebunden (dHg—Hg = 3,41 Å).
    Notes: Mixtures of strontium and mercury in molar ratios of 7:3 have been annealed for 20 days at 520°C. From the pure product Sr3Hg2 single crystals have been obtained. Sr3Hg2 crystallizes in the U3Si2 type of structure (space group P4/mbm); the cell constants are a = 8.883 (2) Å and c = 4.553(1) Å. All of the Hg atoms are involved in Hg2 dumbbells with Hg—Hg distances of 3.41 Å.
