 Title    Solventothermal Synthesis and Structure of the Polymerie Thioarsenates(III) (Et4N)2As6S10 and (Et4N)2As8S13  
 Abstract    Reaction o f (Et4N)C l with AS2S3 and NaaS in acetonitrile at 110°C affords the polym eric thioarsenate(III) (E u N ^ A söS io in which the cyclic [ A s . ^ ] 3-and chainlike [AS3S7]5-trinu-clear molecular building units are linked together through comm on sulphur atoms into infinite double chains. In contrast, reaction o f the same starting materials at higher temperatures (1 80°C) in water leads to formation o f a markedly denser phase (E u N ^ A ss S o , w hose thioarsenate(III) [A sgSi32—] anions exhibit a higher condensation grade. These likew ise double chains are com posed o f cyclic [AS3S6]3-and dinuclear [A s2Ss]4~ units with shared ip-AsS_^ tetrahedra corners. A nalogous treatment o f (Et4N)Cl with A s2Se3 and Na2Se in acetonitrile (T =l 10°C) yields (Et4N)[S eA sS e7].
