2-Formyl-6-meth-oxy-phenyl cinnamate.

ABSTRACT: In the title compound, C(17)H(14)O(4), the C=C bond adopts an E conformation and the dihedral angle between the benzene rings is 73.9 (1)°. The crystal packing features C-H⋯O hydrogen bonds, which generate C(4) chains propagating along the b-axis direction. Weak aromatic π-π stacking inter-actions [centroid-centroid distance = 3.703 (1) Å] are also observed.

(E)-Methyl 2-[(2-formyl-6-meth-oxy-phen-oxy)meth-yl]-3-phenyl-acrylate.

Project description:The title compound, C(19)H(18)O(5), crystallizes with two independent mol-ecules (A and B) in an asymmetric unit in both of which the two aromatic rings are in a bis-ectional orientation as evidenced by the dihedral angle between them [41.7?(1)° in mol-ecule A and 35.6?(1)° in mol-ecule B]. Both mol-ecules adopt an E configuration with respect to the C=C bond. An intra-molecular C-H?O hydrogen-bond occurs in mol-ecule A. The crystal packing features inter-molecular C-H?O inter-actions.

Poly[[di-?-aqua-(?-4-formyl-2-meth-oxy-phenol-ato)disodium] 4-formyl-2-meth-oxy-phenolate].

Project description:In the title coordination polymer, {[Na(2)(C(8)H(7)O(3))(H(2)O)(4)](C(8)H(7)O(3))}(n), all the non-H atoms except the water O atoms lie on a crystallographic mirror plane. One sodium cation is bonded to four water O atoms and one vanillinate O atom in a distorted square-based pyramidal arrangement; the other Na(+) ion is six-coordinated by four water O atoms and two vanillinate O atoms in an irregular geometry. One of the vanillinate anions is directly bonded to two sodium ions, whilst the other only inter-acts with the polymeric network by way of hydrogen bonds. In the crystal, a two-dimensional polymeric array is formed; this is reinforced by O-H?O hydrogen bonds, which generate R(2) (1)(6) and R(2) (2)(20) loops.
