HAFNER, P and RANGE, KJ (1994) NA3AS REVISITED - HIGH-PRESSURE SYNTHESIS OF SINGLE-CRYSTALS AND STRUCTURE REFINEMENT. JOURNAL OF ALLOYS AND COMPOUNDS, 216 (1). pp. 7-10. ISSN 0925-8388,
Full text not available from this repository.Abstract
Single crystals of Na3As have been obtained from the elements by high-pressure-high-temperature reaction in a modified Belt-type apparatus. The compound crystallizes hexagonally, space group P6(3)cm, with a=8.7838(8) Angstrom, c=8.9990(12) Angstrom, c/a=1.0245 and Z=6. The structure refinement (R=0.027, R(w)=0.017 for 303 absorption-corrected unique reflections) shows unequivocally that Na3As is isostructural with Cu3P and that the structure models proposed by Brauer and Zintl (referred to as ''Na3As type'' in the literature, space group P6(3)/mmc) and Mansmann (anti-LaF3, type, space group P (3) over bar cl) are wrong.
