摘要
The crystal structure of the 1:1 ethanol betulin solvate, a widely spread natural compound, is determined. The betulin solvate crystallizes in orthorhombic symmetry in the P2(1)2(1)2(1) space group, Z= 4. The unit cell parameters are as follows: a = 7.0159(1) , b = 12.4425(2) , c = 33.7500(5) ; V = 2946.22(8) (3). Betulin molecules are hydrogen bonded to each other and ethanol molecules, as a result of which the layers are distinguished in the structure, which are perpendicular to the crystallographic direction. Inside the layer, all molecules are hydrogen bonded, while the layers are linked by van der Waals interactions.
