 Title    Über Erdalkalimetallverbindungen des l,l-Dicyanoethylen-2,2-dithiolats, III+ Die Kristallstruktur von SrS2C4N2 * 5 H20  
 Abstract    By reaction of CS2 with m aleonitrile in presence of sodium ethanolate in ethanol, N a2S2C4N 2 is obtained. SrS2C4N2-5 H 20 was synthesized by reaction of Sr(NCS) 2 with N a2S2C4N2 in ethanol. It crystallizes monoclinically, space group P2!/c, with a = 9.201(2), b — 9.990(6), c = 14.605(5) Ä,/3 = 122.3(3)°, Z = 4. The com pound is isotypical with CaS2C4N2-5 H 20 . A structural model based on equivalent metal positions was refined to R -0.057. The crystal structure contains layers of nearly planar [S2C = C (C N)2]2' anions held together by interspersed Sr2+ cations in a tricapped trigonal prismatic surrounding of 6 0 and 3N atoms. The S atom s of the ligand are not included in the coordination sphere of Sr2+ but are involved in several O — H -S hydrogen bonds.
