Synthesis and Structure of [ImNCS2K] (ImN = 1,3-Dimethylimidazoline-2-imino): a Novel Potassium DithiocarbiminateThe reaction of the 2-iminoimidazoline 4 with KMe gives the potassium imidate 7 from which the potassium 1,1-dithiolate 8 is obtained in almost quantitative yield. Crystals of C6H8N3S2K · 1/6 CH3CN (8 · 1/6 CH3CN) are triclinic, space group P1, Z = 6, a = 10.988(4), b = 13.597(8), c = 13.622(9) Å, α = 113.003, β = 105.53(3), γ = 105.62(3)°, V = 1636.90 Å3. The structure consists of a complicated 3-dimensional framework in which the K2 units bridged by the four sulfur atoms of two thiolate ligands are connected by nitrogen and sulfur bridges.
Notes:
Die Umsetzung des 2-Iminoimidazolins 4 mit KMe ergibt das Kaliumimidat 7, aus dem das Kalium-1,1-dithiolat 8 in fast quantitativer Ausbeute erhältlich ist. C6H8N3S2K · 1/6 CH3CN (8 · 1/6 CH3CN) kristallisiert triklin, Raumgruppe P1, Z = 6, a = 10.988(4), b = 13.597(8), c = 13.622(9) Å, α = 113.00(3), β = 105.53(3), γ = 105.62(3)°, V = 1636.90 Å3. Die komplexe Raumnetzstruktur besteht aus den durch die 4 Schwefelatome zweier Dithiolat-Liganden verbrückten K2-Einheiten, die ihrerseits über Stickstoff- und Schwefelatome verbunden sind.
