    Description / Table of Contents: Preparation and Crystal Structure of a New Isomeric Form of As4S4As4S4(II) was prepared by melting of the pure elements As and S in the atomic ratio 1:1 at the temperature range 500°-600°C and a quickly cooling to the room temperature. Yellow-orange coloured and very thin platy single crystals were recrystallized from a CS2 solution. The crystal parameters are: a = 11.193, b = 9.994, c = 7.153 Å and β = 92.8°. The space group in P21/n (No. 14).The molecule can be principally deduced from the As4-tetraedron. By the connection of the folded plane SAs3 to the platy pyramide S3As the cage structure of the As4S4(II) molecule will be built.
    Notes: As4S4(II) wird durch Zusammenschmelzen von elementarem As und S im Atomverhältnis 1:1 bei 500-600°C und schnelle Abkühlung erhalten. Aus der Lösung in CS2 rekristallisieren gelb-orangefarbene Einkristalle in Form von sehr dünnen Plättchen. Die Kristallparameter sind a = 11,193, b = 9,994, c = 7,153 Å, β = 92,8°; die Raumgruppe ist P21/n (Nr. 14).Das Molekül kann prinzipiell aus dem As4-Tetraeder abgeleitet werden. Ankopplung eines gewellten SAs3-Vierecks mit einer stumpfen S3As-Pyramide ergibt das Käfigmolekül As4S4 (II).
