Grothe, Michael and Korber, Nikolaus (2003) As12Se44-: a new selenoarsenate anion with a polyarsenic cage in the compound [Co(NH3)(6)](2)As12Se4 center dot 12 NH3. ZEITSCHRIFT FUR ANORGANISCHE UND ALLGEMEINE CHEMIE, 629 (3). pp. 399-402. ISSN 0044-2313

Orange coloured crystals of [Co(NH3)(6)](2)As12Se4. 12 NH3 were prepared by the reduction of As4Se4 with a solution of sodium in liquid ammonia and subsequent precipitation with CoBr2. The X-ray structure determination shows them to contain the selenoarsenate anion As12Se44-, which consists of a central As-12-cage with four exo-bonded, formally negatively charged Se atoms. The structure of the As-12-cage is equivalent to the main polyphosphorus building unit of a known organopolyphosphane and of tubular P-12 in the compound (CUI)(3)P-12.
