The microstructures of R3(Fe, M)29 compounds in the compositional range between 2-17 and 1-12 phases have been studied by using High-Resolution Transmission Electron Microscopy(HRTEM). The purpose of this paper is to investigate the crystal structures and the lattice constant of Sm3(Fe, Co, M)29(M=Cr, V) compounds and their nitrided ones. As a result, it was revealed by the electron diffraction and lattice image analysis that the crystal of the main phase in the nitrided samples has a hexagonal structure and its crystal form is not influenced by the nitrifying. The lattice constant of Sm3(Fe0.75Co0.10Cr0.15)29 are a=2.432nm and c=2.088nm, and the unit cell is composed by the stacking five cells of CaCu5 along a and c axes.
