4-Formyl-2-nitrophenyl benzoate
In the title nitroaryl benzoate derivative, C14H9NO5, the aromatic rings form a dihedral angle of 46.37 (8)°. The central ester moiety, -C-(C=O)-O-, is essentially planar (r.m.s. deviation for all non-H atoms = 0.0283 Å) and forms a dihedral angle of 54.06 (9)° with the 4-formyl-2-nitro-phenyl ring and 7.99 (19)° with the benzoate ring. In the crystal, mol-ecules are inter-twined by weak C-H⋯O ...
متن کامل2-Formyl-6-methoxyphenyl cinnamate
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.
متن کامل4-Formyl-2-nitrophenyl 2-chlorobenzoate
In the title compound, C14H8ClNO5, the benzene rings form a dihedral angle of 19.55 (9)°. The mean plane of the central ester group [r.m.s. deviation = 0.024 Å] forms dihedral angles of 53.28 (13) and 36.93 (16)°, respectively, with the nitro- and chloro-substituted rings. The nitro group forms a dihedral angle of 19.24 (19)° with the benzene ring to which it is attached. In the crystal, mol-ec...
متن کاملPoly[[di-μ-aqua-(μ-4-formyl-2-methoxyphenolato)disodium] 4-formyl-2-methoxyphenolate]
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 ir...
متن کاملChlorido(2-formyl-6-hydroxyphenyl-κC 1)mercury(II)
In the planar [r.m.s. deviation 0.0265 Å] title compound, [Hg(C(7)H(5)O(2))Cl], the Hg(II) atom shows a typical linear coordination by a C atom of a benzene ring and a Cl atom. The benzene C atom and the aldehyde O atom chelate the Hg(II) atom by assuming the Hg⋯O separation of 2.817 (9) Å as a weak intra-molecular coordination bonding distance. The resulting five-membered metallacycle is nearl...
