Powder data for synthetic analogue of a mineral nickelphosphide

Author:

Abstract

All known occurrences of nickelphosphide (Ni,Fe)3P—a mineral encountered mainly in meteoritic irons—represent relatively small grains, which prevents acquiring powder data of a reasonable quality. Synthetic analogues of this mineral, corresponding chemically to that found in the meteorite Vicenice, have been synthesized. Powder data collected using a standard laboratory diffractometer in the Bragg–Brentano geometry are presented. The space group of nickelphosphide is identical to that of schreibersite (Fe,Ni,Co)3P and synthetic Ni3P—I4. The unit-cell dimensions refined from the powder data are a=9.0168(1) Å, c=4.4501(1) Å, and V=361.80(1) Å3, with Z=8.
