An x-ray diffraction study of nickel cyanide ammoniate

Abstract
The structure of the nickel cyanide ammoniate complex has been determined by x-ray diffraction methods. The cell is tetragonal with a = 7.222 Å and o = 17.42 Å. The nickel and cyanide atoms pack in extended square arrays perpendicular to the c axis. The structure is compared with the structures of its hydrate and benzene clathrate which have been determined by other workers.
