Magnetic structure of Pr6Fe13Ge at room temperature has been investigated by magnetic measurement, M ssbauer effect and neutron diffraction. Magnetic atoms are closely packed up and down the mirror planes at z=0 and 1/2 and separated by the non-magnetic atoms located on the planes at z=1/4 and 3/4, which constructs an M/NM/M sandwich structure (M: magnetic, NM: non-magnetic). The intralayer magnetic moments couple ferromagnetically and are out of ab plane at a small angle so as to form a component along c-axis. The interlayer coupling is antiferromagnetic for the ab component while ferromagnetic for the c component.
