      5α-cyano-3-keto-10-methyl-octahydronaphthalene, C12H17NO, crystallizes in monoclinic space group P21·c witha = 7.28(2),b = 7.48(2),c = 19.29(5)Å, β= 88.0(2)∘ and has four molecules per unit cell. The structure was solved by direct methods and refined to anR-value of 11.4% by block diagonal least-squares method for 565 observed reflections recorded by film method. The cyano group iscis to methyl group at C(10) and the fused rings have a chair conformation. The carbonitrile fragment is almost linear, the angle C-C= N being 175.6(3.0)∘.
