Curcumenol from Curcuma zedoaria: a second monoclinic modification.

Project description:The title compound, systematic name 9-isopropyl-idene-2,6-dimethyl-11-oxatricyclo-[6.2.1.0(1,5)]undec-6-en-8-ol, C(15)H(22)O(2), which crystallizes with two mol-ecules of similar conformation in the asymmetric unit, features three fused rings, two of which are five-membered and the third six-membered. Of the two five-membered rings, the one with an O atom has a distinct envelope shape (with the O atom representing the flap). The six-membered ring is also envelope-shaped as it shares a common O atom with the five-membered ring. In the crystal, the two independent mol-ecules are linked by a pair of O-H?O hydrogen bonds, generating a dimer.

N'-(3-Methyl-quinoxalin-2-yl)-N'-phenyl-benzohydrazide.

Project description:In the crystal structure of the title compound, C(22)H(18)N(4)O, the quinoxaline system makes dihedral angles of 86.59?(7) and 63.37?(9)° with the benzohydrazide and phenyl rings, respectively. The benzohydrazide ring makes a dihedral angle of 72.46?(10)° with the phenyl ring. The crystal structure is stabilized by inter-molecular N-H?O hydrogen bonds, C-H?O contacts and C-H?? inter-actions.

Second monoclinic form of (E)-3-(4-fluoro-phen-yl)-1-phenyl-prop-2-en-1-one.

Project description:The unit-cell dimensions and space group of the second monoclinic polymorph of the title compound, C15H11FO, differ from those of the previously reported form [Jing (2009 ?). Acta Cryst. E65, o2515]. The title compound shows an E conformation of the C=C bond with the 4-fluoro-phenyl group opposite to the benzoyl group. The torsion angle of between the planes of the 4-fluoro-phenyl and benzoyl groups is 10.53?(6)°. In the crystal, weak C-H?O and C-H?F inter-actions form a cross-linked packing motif, building sheets parallel to (-102).
