    Description / Table of Contents: Crystal Structures of Two Forms of In5Mo18O28 and TwinningIn5Mo18O28 is prepared from In, Mo and MoO2 at 1 150°C in an evacuated quartz glass ampoule. X-ray investigations on single crystals show monoclinic symmetry (a = 1 323.13(9), b = 951.88(10), c = 989.48(8) pm, β = 100.976(4)°, space group P 21/c (No. 14)) for form 1. The second form (2) crystallizes in the orthorhombic system (space group Pmcn (No. 62), a = 2 596.6(5), b = 952.0(2), c = 989.6(2) pm). Twinning and charge balances are discussed.
    Notes: Beim Tempern von Indium mit Molybdän und Molybdändioxid in verschlossenen Quarzglasampullen bei 1 150°C erhält man die Verbindung In5Mo18O28. Untersuchungen an Einkristallen ergeben für die Modifikation 1 eine monokline Struktur (a = 1 323,13(9), b = 951,88(10), c = 989,48(8) pm, β = 100,976(4)°, Raumgruppe P 21/c (Nr. 14)). Die zweite Modifikation (2) kristallisiert orthorhombisch in der Raumgruppe Pmcn (Nr. 62, a = 2 596,6(5), b = 952,0(2), c = 989,6(2) pm). Zwillingsbildung und Ladungsbilanzen werden diskutiert.
