Abstract

Neutron and X-ray intensities of NH4F were measured at -196°C and -155°C respectively. The wurtzite type structure and space group P63mc were confirmed. The displacement of the two h.c.p. sublattices, formed by each of the F-- and NH+4- ions, is such that all bond-distances are equivalent. The N-H bond distances as found from the X-ray data are about 0.1 Å shorter than those obtained from the neutron data. The final weighted R values were 1.9% and 2.6% for the X-ray and neutron data respectively.
