Abstract

The crystal structure of 17α-methyltestosterone hemihydrate, C20H30O2·1/2H2O, has been determined:M r =312.5, space groupP21212121,a=6.374(2),b=12.807(2),c=43.398(5)Å,V c =3543(2)Å3,Z=8,D x =1.172 mg−3, CuKα radiation (\(\bar \lambda \) = 1.54184 Å),μ(CuKα)=5.5 cm−1,F(000)=1376. The structure was solved usingMultan. The final conventionalR=0.053 (R w =0.052) for 3634 reflections. The structure contains two crystallographically independent molecules in the asymmetric part of the unit cell that have almost identical geometry.
