title: Bis(adamantan-1-aminium) tetrachloridozincate(II) 18-crown-6 monohydrate clathrate.
abstract: The structure of the title compound [systematic name: bis(adamantan-1-aminium) tetrachloridozincate(II)-1,4,7,10,13,16-hexaoxacyclooctadecane-water (1/1/1)], (C(10)H(18)N)(2)[ZnCl(4)] x C(12)H(24)O(6) x H(2)O, consists of supramolecular rotator-stator assemblies and ribbons of hydrogen bonds parallel to [010]. The assemblies are composed of one protonated adamantan-1-aminium cation and one crown ether molecule (1,4,7,10,13,16-hexaoxacyclooctadecane) to give an overall [(C(10)H(18)N)(18-crown-6)](+) cation. The -NH(3)(+) group of the cation nests in the crown and links to the crown-ether O atoms through N-H...O hydrogen bonds. The 18-crown-6 ring adopts a pseudo-C(3v) conformation. The second adamantan-1-aminium forms part of ribbons of adamantan-1-aminium-water-tetrachloridozincate units which are interconnected by O-H...Cl, N-H...O and N-H...Cl hydrogen bonds via three different continuous rings with R(5)(4)(12), R(4)(3)(10) and R(3)(3)(8) motifs.
