Abstract

The crystal structure of the modified steroid, 20 oximino-5α pregn-eno [3, 4-c] 1′2′5′ oxadiazole (HS998) using X-ray diffraction is reported. HS998 crystallizes in the orthorhombic space groupP212121, having cell parametersa=13.465(3),b=18.792(4),c=7.598(2) Å;Z=4. The structure was solved by direct methods and refined by full matrix least squares toR=0.060 for 3478 reflections.
