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

ABSTRACT: In the title heteroaryl chalcone derivative, C(17)H(17)NO(4), the dihedral angle between the pyridine and benzene rings is 10.82?(5)°. The two meth-oxy groups at the meta positions are essentially coplanar with the attached benzene rings [C-O-C-C torsion angles = -0.97?(14) and 179.47?(9)°], whereas the meth-oxy group at the para position is twisted from the attached ring with a C-O-C-C torsion angle of -104.48?(11)°. A C-H?O close contact involving two of the meth-oxy groups generates an S(6) ring motif. In the crystal, mol-ecules are linked by weak C-H?O inter-actions into columns along the b axis.

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)°.

While no classical hydrogen bonds are present, three weak inter-molecular C-H?O inter-actions and weak C-H?Br and C-H?Cg ?-ring stacking inter-actions [C-H?Cg distance = 3.377?(2)?Å] are observed, which contribute to the stability of crystal packing.

(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.

In the crystal, mol-ecules are linked by weak C-H?O bonds to stack along the b axis and further C-H?O inter-actions consolidate the structure.

(2E)-1-(Pyridin-2-yl)-3-(2,4,6-trimeth-oxy-phen-yl)prop-2-en-1-one.

Project description:The title heteroaryl chalcone derivative, C(17)H(17)NO(4), is a condensation product of 2-acetyl-pyridine and 2,4,6-trimeth-oxy-benzaldehyde.

In the crystal, the mol-ecules are linked by weak C-H?O inter-actions into anti-parallel face-to-face pairs. Adjacent pairs are further connected into sheets parallel to the ab plane.
