Crystals o f the complex [K (benzo-18-crown-6][Zn(CN)3] H2O were obtained from a solution o f Zn(CN)2, KCN, and benzo-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), β = 87,38(4), 7 = 75,46(5). Each Zn atom is bonded to one bridging cyanide ion to give chains -Zn(CN)Zn -, and to two terminal CN groups. The N atom of one of the terminal CN groups interacts with a potassium ion o f the [K (benzo-18-crown-6)]+ unit. The coordination spheres of the K ions are completed by water molecules, which in turn form hydrogen bonds to N atoms of terminal CN groups of neighbouring chains, whereby puckered sheets are formed
