    Description / Table of Contents: Methylation and Oxidation of 1,1-Dicyanoethylene-2,2-oxo-thiolate Dianion: Preparative and Structural InvestigationsThe reaction of K2[S(O)C=C(CN)2] with CH3I yields the mono-S-methylproduct. The potassium salt crystallizes in the space group P21/c with a = 3.951(1), b = 15.623(3), c = 11.916(2) Å, β = 93.46(3)° and Z = 4. The methyl group is directed towards the oxygen atom.Potassium has a monocapped trigonal prismatic coordination: 5 N and 2 O atoms.The oxidation of 1,1-Dicyanoethylene-2,2-oxo-thiolate yields the dimere [(NC)2C=C(O)—S—S—(O)C=C(CN)2]2- in the first oxidation step. An X-ray crystal structure determination shows that the anion consists of two planar [S(O)C=C(CN)2] units which are oriented perpendicular within the anion.
    Notes: Die Reaktion Von K2[S(O)C=C(CN)2] mit CH3I liefert das Mono-S-methylprodukt, das in Form des Kaliumsalzes strukturell charakterisiert wurde. Die Verbindung kristallisiert in der Raumgruppe P21/c mit a = 3,951(1), b = 15,623(3), c = 11,916(2) Å, β = 93,46(3)° und Z = 4. Die Methylgruppe zeigt zum Sauerstoffatom des Monoanions. Kalium ist siebenfach in Form eines monocapped trigonalen Prismas Von 5 N- und 2 O-Atomen umgeben.Die Oxydation Von 1,1-Dicyanoethylen-2,2-oxo-thiolat liefert im Primärschritt das Dimere [(NC)2C=C(O)—S—S—(O)C=C(CN)2]2-, dessen Konstitution röntgenographisch aufgeklärt wurde. Im Dimeren sind die [S(O)C=C(CN)2]-Einheiten planar und relative zueinander senkrecht angeordnet.
