Abstract
The crystal belongs to space group P212121, and the cell dimensions are a = 8.5300(5), b = 11.4516(9) and c = 23.893(1)Å. The final R value is 0.047. There are two crystallographically independent molecules in an asymmetric unit. The pyranose rings in both molecules take chair conformations. The nitrosourea moieties are planar. There is an extensive hydrogen network in the crystal.
