X-ray powder diffraction data and crystal data of polymorphic form 2 of carnidazole

The indexed powder diffraction pattern and related crystallographic data for polymorphic form 2 of carnidazole (C8H12N4O3S) are reported, as a first step in the structure determination by powder diffraction methods. The unit cell dimensions were determined from high resolution synchrotron powder diffraction data (lambda=0.079 998 0 nm) and evaluated by indexing programs. The monoclinic cell found for this polymorph is a=1.3908(2) nm, b=08094(2) nm, c=1.0645(2) nm, beta=110.82(2)degrees, V=1.12015(27) nm(3), Z=4, Dx=1.445 Mg/m(3).
