Crystal structure of intercalated four-stranded d(C3T) at 1.4 angstroms resolution. 
Proc.Natl.Acad.Sci.USA, 91, pp. 11636 - 11640, 1994.

Experimental Information:

X-RAY DIFFRACTION

Space Group:

C 2 2 21

Cell Constants:

a = 28.281   b = 44.341   c = 50.472 (Ångstroms)

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

Refinement:

The structure was refined using the X-PLOR program. The R value is 0.177 for 5013 reflections in the resolution range 10.0 to 1.4 Ångstroms with Fobs >  2.0 sigma(Fobs) and with I >  0.0 sigma(I)
