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

ABSTRACT: The title mol-ecule, C(16)H(16)O(5), is twisted; the dihedral angle between the furan and 3,4,5-trimeth-oxy-phenyl rings is 12.14?(13)°. The two meth-oxy groups at the meta positions of the benzene ring are close to being coplanar with the ring [C-O-C-C = -0.6?(3) and 1.4?(3)°], whereas the third meth-oxy group, at the para position, is (+)-anti-clinal with respect to the benzene ring [C-O-C-C = 104.9?(2)°]. 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.

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)°.

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.
