A polycrystalline sample of RbND2 was prepared by reaction of liquid ND3 and Rb (320 K, 4 d). Rietveld refine ment of neutron powder diffraction data collected on the E2 (HMI-BENSC, Berlin) yielded the deuterium positions and allowed the temperature factors of all atoms to be refined anisotropically: space group P2(1)/m, Z = 2, a = 4.846(1) Angstrom, b = 4.136(1) Angstrom, c = 6.396(2) Angstrom, beta = 98.051(7)degrees, N(I/sigma((1)) > 1) = 179,N(Var.) = 25, R-p = 0.025, WRp = 0.032, R-B(I/sigma((1)) > 1) = 0.095.In a monoclinic distorted rock salt structure the amide ions are oriented antiferroelectrically in almost planar zick-zack chains.
