N2  - Neutron powder diffraction data, collected both at room temperature and at 10 K, for Pb10(PO4)6(OH)2, have been used to refine structural parameters by the Rietveld method. The compound is hexagonal at both temperatures, P 63/m; Z = 1, a = 9&#183;8828(4); 9&#183;8355(3) and c= 7&#183;4406(2); 7&#183;4100(1) &#197; at 295 and 10 K, respectively. The results show the displacement of the hydroxide group from the Pb(2) triangle is greater than that expected from steric arguments alone.
