Abstract: The single crystal of 15-methyl-bicyclo[10, 3, 0]pentadec-1 (12)-en-13-one belongs to rhonoclinic system, space group P21/n, α = 0. 4838(1) nm, 6=1. 3949(2) nm, c=2. 1645(4) nm, β=92. 07(1)°, Z = 4. The molecule of such compound is bicyclic and linked by a C=C bond, one cycle is a planary five-membered ring and the other is a cyclododecene part. The molecular conformation in the single crystal is compatible to the most stable one of the conformational isomers calculated by molecular mechanics.
