چکیده

The title compound, C(22)H(28)O, was isolated from the aerial part of Inula viscosa- (L) Aiton [or Dittrichia viscosa- (L) Greuter]. The cyclo-hexene ring has a half-chair conformation, whereas the cyclo-hexane ring displays a chair conformation being substituted at position 2 by a 3-(4-methyl-phen-yl)prop-2-enoyl group. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains in the [010] direction.

The crystal structures of two chalcones: (2E)-1-(5-chloro­thio­phen-2-yl)-3-(2-methyl­phen­yl)prop-2-en-1-one and (2E)-1-(anthracen-9-yl)-3-[4-(propan-2-yl)phen­yl]prop-2-en-1-one

In the crystal of compound (I), C14H11ClOS, mol-ecules are linked by C-H⋯O hydrogen bonds to form simple C(5) chains. Compound (II), C26H22O, crystallizes with Z' = 2 in space group P-1; one of the mol-ecules is fully ordered but the other is disordered over two sets of atomic sites having occupancies 0.644 (3) and 0.356 (3). The two disordered components differ from one another in the orientat...
