    Description / Table of Contents: On Chalcogenolates. 148. Reaction of Formamide with Carbon Disulfide. 2. Crystal Structure of Potassium N-Formyl DithiocarbamateK[S2C—NH—CO—H] crystallizes with Z = 16 in the monoclinic space group Cc with cell dimensions a = 13.187(13) Å, b = 12.928(3) Å, c = 13.962(6) Å, and β = 101.75 (3)°. The crystal structure has been determined from single crystal X-ray data measured at 20°C and refined to a conventional R of 0.034 for 1857 independent reflections (Rw = 0.038).The compound crystallizes by building a super-structure, which is based on an H-bridged 16-membered ring-system, formed by four[S2C—NH—CO—H]- anions. Two different binuclear K+ coordination polyhedra are formed with two oxygen and two sulfur atoms in common.
    Notes: K[S2C—NH—CO—H] kristallisiert monoklin mit Z = 16 in der Raumgruppe Cc, Gitterdimensionen: a = 13,187(13) Å, b = 12,928(3) Å, c = 13,962(6) Å, β = 101,75(3)°. Die Kristallstruktur wurde aus röntgenographischen Einkristalldaten (20°C) unter Verwendung von 1857 unabhängigen Reflexen bestimmt und bis zu einem konventionellen Gütefaktor von R = 0,034 verfeinert (Rw = 0,038).Es liegt eine Überstruktur vor, die dadurch entsteht, daß vier [S2C—NH—CO—H]--Anionen über Wasserstoffbrücken N—H⃛O und N—H⃛S zu einem planaren, 16gliedrigen Ring miteinander verbunden sind. Jedes K+-Ion ist von zwei O- und sieben S-Atomen in unregelmäßiger Koordination umgeben. Es werden zwei verschiedene zweikernige K+-Koordinationspolyeder gebildet, die jeweils zwei O- und zwei S-Atome gemeinsam haben.
