    Description / Table of Contents: On Chalcogenolates. 170. Reaction of N,N′-Diphenyl Formamidine with Carbon Disulfide 3. Crystal Structure of Potassium N,N′-Diphenyl N-Formimidoyl Dithiocarbamate · DioxaneThe title compound K[S2C—N(C6H5)—CH=NC6H5] · C4H8O2 crystallizes with Z = 4 in the monoclinic space group P21/a with cell dimensions a = 10.703(2) Å, b = 18.068(3) Å, c = 10.504(3) Å, β = 100.96(3)°. The crystal structure has been determined from single crystal X-ray data measured at 20°C and refined to a conventional R of 0.052 for 4556 independent reflections (Rw = 0.054).The K+ cation is surrounded of one oxygen, one nitrogen, and three sulfur atoms to form a distorted trigonal bipyramid. The S2CNCN part of the anion, which exists as E, E conformer, is plane. The dioxane molecule has chair conformation without symmetry centre.
    Notes: Die Titelverbindung K[S2C—N(C6H5)—CH=NC6H5] · C4H8O2 kristallisiert monoklin mit Z = 4 in der Raumgruppe P21/a; Gitterdimensionen: a = 10,703(2) Å, b = 18,068(3) Å, c = 10,504(3) Å, β = 100,96(3)°. Die Kristallstruktur wurde aus röntgenographischen Einkristalldaten (20°C) unter Verwendung von 4556 symmetrieunabhängigen Reflexen bestimmt und bis zu einem konventionellen Gütefaktor von R = 0,052 verfeinert (Rw = 0,054).In der Verbindung ist das K+-Kation verzerrt trigonal-bipyramidal von einem Stickstoff-, einem Sauerstoff- und drei Schwefel-Atomen umgeben. Das Anion liegt in der E,E-Form vor, dessen S2CNCN-Teil planar ist. Das Dioxan-Molekül besitzt Sessel-Konformation und ist nicht zentrosymmetrisch aufgebaut.
