(E)-1-[4-(Prop-2-yn-1-yl-oxy)phen-yl]-3-(3,4,5-trimeth-oxy-phen-yl)prop-2-en-1-one.

ABSTRACT: The mol-ecule of the title chalcone derivative, C(21)H(20)O(5), consists of two substituted aromatic rings bridged by a prop-2-en-1-one group. The dihedral angle between the two benzene rings is 28.7 (7)°. In the crystal, mol-ecules are linked into C(10) chains running along the a axis by inter-molecular C-H⋯O hydrogen bonds, and the chains are cross-linked via C-H⋯π inter-actions.

Project description:In the chalcone title compound, C(18)H(17)BrO(4), the dihedral angle between the mean planes of the 2-bromo- and 3,4,5-trimethoxy-substituted benzene rings is 89.3?(1)°.

(E)-1-(2-Amino-phen-yl)-3-(3,4,5-trimeth-oxy-phen-yl)prop-2-en-1-one.

Project description:In the asymmetric unit of the title chalcone derivative, C(18)H(19)NO(4), there are three crystallographically independent mol-ecules (mol-ecules A, B and C). In mol-ecule A, the dihedral angle between two benzene rings is 12.22 (10)° and the plane of the central prop-2-en-1-one unit makes dihedral angles of 11.02 (13) and 2.64 (12)° with the two adjacent benzene rings. The corresponding angles in mol-ecule B are 12.35 (10), 18.78 (12) and 7.29 (12)°, respectively, and those in mol-ecule C are 15.40 (10), 15.62 (3) and 3.19 (13)°. In each mol-ecule, an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, the mol-ecules B are linked by inter-molecular N-H⋯O hydrogen bonds into a zigzag chain along the c axis, while the mol-ecules A and C are linked together via an N-H⋯O hydrogen bond into a dimer. Adjacent dimers are further connected by N-H⋯N hydrogen bonds into a three-dimensional network. Weak C-H⋯O and C-H⋯π inter-actions are also observed.

Project description:In the title compound, C(18)H(16)Cl(2)O(4), the dihedral angle between the benzene rings is 82.40 (4)°.
