We present the crystal structure refinements from single crystal X-ray diffraction data for schreibersite grains from iron meteorites Acuna, Carlton, Hex River Mts., Odessa, Sikhote Alin, and Toluca aiming for the determination of the absolute structure of the examined crystals. Unit-cell parameter a and volume of the unit cell V, as well as certain topological structural parameters tightly correlate with Fe3P content. Unit-cell parameter c, on the other hand, does not show such strong correlation. Eight of the nine crystal structure refinements allowed unambiguous absolute structure assignment. Six of the eight unambiguous absolute structure determinations indicated inverted atomic arrangement compared to that reported in earlier structure refinements.
