The crystal structure of the title compound, K[Ag(CN)(2)].C(12)H(24)O(6), conventionally denoted K(18-crown-6)Ag(CN)(2), where 18-crown-6 is 1,4,7,10,13,16-hexaoxacyclooctadecane, is characterized by closely packed linear chains formed by the coordination of the nitrile N atoms of the Ag(CN)(2) anions to the K(+) cations. The K atoms lie on centers of inversion and are additionally bound to the six O atoms of the crown ether.
