Magnetic structures in an antiperovskite system MnCuGeN with a large magneto-volume effect above 
=0.15 have been studied by neutron powder diffraction measurement. The present neutron study revealed that not only a cubic crystal structure, but also a 
antiperovskite spin structure, is a key ingredient of the large magneto-volume effect in this itinerant electron system. The large magneto-volume effect is possibly ascribed to the geometrical frustration originating from the corner-shared octahedra of the antiperovskite sturucture.
