 Title    Kristallstruktur des "supramolekularen" Komplexes [K(Benzo-18-krone-6)][Zn(CN)3]*H20 mit einem polymeren kettenförmigen Tricyanozincat-Anion Crystal Structure of the "Supramolecular" Complex [K(benzo-18-crown-6)][Zn(CN)3] *H20 with a Polymeric Tricyano Zincate Anion with Chain Structure  
 Abstract    Crystals o f the com plex [K (benzo-18-crown-6][Zn(CN)3] H20 were obtained from a solution o f Z n(C N)2, KCN, and b en zo-18-crown-6 in water/methanol. The compound crystallizes in the triclinic space group PI (no. 2),: Z = 2, a = 818,6(5), b = 1236,7(8), c = 1359,6(6) pm, a = 67,02(4), ß = 87,38(4), 7 = 75,46(5). Each Zn atom is bonded to one bridging cyanide ion to give chains -Z n (C N)Z n -, and to two terminal CN groups. The N atom o f one o f the terminal CN groups interacts with a potassium ion o f the [K (benzo-18-crow n-6)]+ unit. The coordination spheres o f the K ions are completed by water molecules, which in turn form hydrogen bonds to N atoms o f terminal CN groups o f neighbouring chains, whereby puckered sheets are formed.
