Cell(Cambridge,Mass.), 81, pp. 991 - 1002, 1995.

Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 31 2 1

Cell Constants:

a = 64.98   b = 64.98   c = 138.14 (Ångstroms)

α = 90.0   β = 90.0   γ = 120.0 (degrees)

Refinement:

The structure was refined using the X-PLOR 3.1 program. The R value is 0.251 for 6199 reflections in the resolution range 15.0 to 3.1 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
