Table 1. Percentage Changes in the Unit-Cell Parameters, in the Areas of the ab, ac, and bc Faces of the Unit Cell, and in the Cell Volumes for the Two Reactions LiCoPO₄ => Li_2/3CoPO₄ and Li_2/3CoPO₄ => CoPO₄^a.

	%
	Δa	Δb	Δc	Δab	Δac	Δbc	Δvolume
LiCoPO4 - Li2/3CoPO4	1.2	1.2	–0.4	2.4	0.8	0.7	2.0
Li2/3CoPO4 – CoPO4	5.1	1.1	–0.9	6.1	4.2	0.2	5.3

^aThe changes are calculated relative to the LiCoPO₄ and Li_2/3CoPO₄ structures, respectively.
