Abstract
The crystal structure of hexagonal LuMnO3 at room temperature is isomorphou s with YMnO3 and deviates in important details from the early work of Yakel et al. [Acta Cryst. (1963), 16, 957-962]. Mn is near the centre of its oxy gen coordination environment. On the threefold axes, the apical O-Lu bonds have alternating long and short bond lengths, leading to ferroelectric beha viour. The sample studied was composed of almost equal volumes of inversion twins.
