Atomic ordering of nitrogen in V_8N precipitated in a VN_<0.04> specimen was investigated by electron diffraction/microscopy, and a superstructure consisting of 4×4×1 array of distorted bcc metal cells was proposed. The nitrogen atoms were found to be situated in pairs at the special octahedral interstitial sites of the metal lattice. High resolution many-beam images of V_8N were observed using a 1 MV electron microscope. Static displacements of vanadium atoms adjoining the nitrogen atoms were estimated from matching the observed images with multislice computations based on the proposed structure model.
