X-ray diffraction experiments on the molten iron sulfide, FeS, were conducted up to 5 GPa by using synchrotron radiation. The correlation function g (r) for molten FeS was obtained just above the melting point. The near-neighbor structure of molten FeS does not change with pressure up to 5 GPa. The average nearest-neighbor distance is about 2. 4 Å, which is correspond to the atomic distance between Fe and S. The average coordination number is about six. In FeS melt, Fe and S atoms surround each other with an octahedral coordination in near-neighbor region.
