Table 1. Data-collection statistics.

Values in parentheses are for the outer resolution shell.

	Crystal form A	Crystal form B
Resolution range (Å)	15–1.67 (1.70–1.67)	15–1.95 (1.98–1.95)
No. of measured reflections	504954	231882
No. of unique reflections	86906	96563
Completeness	90.7 (81.1)	79.7 (81.5)
I > 3σ(I) (%)	73.6 (34.2)	61.9 (40.8)
I/σ(I)	25.1 (3.4)	16.6 (2.2)
Rsym† (%)	5.6 (25.1)	4.6 (37.2)

^† R _sym = , where I(h) is the intensity of reflection h, is the sum over all reflections and is the sum over J measurements of the reflection.
