(E)-Methyl 2-[(2-formyl-6-methoxyphenoxy)methyl]-3-phenylacrylate
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-...

In the title compound, C(18)H(16)O(2), the heterocyclic ring of the chroman-2-one system adopts a slightly distorted screw-boat conformation. The dihedral angle between the least-squares planes of the coumarin ring system and the benzene ring is 67.5 (1)°. The crystal packing features C-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric R(2) (2)(8) dimers, and C-H⋯π inter-actions.

In the title compound, C(20)H(21)NO(5), the dihedral angle between the mean planes through the two rings is 47.1 (8)°. The enoate group assumes an extended conformation. The hy-droxy-ethanimine group is essentially coplanar with the benzene ring, the largest deviation from the mean plane being 0.061 (1) Å for the O atom. In the crystal, mol-ecules are linked into cyclic centrosymmetric dimers w...

In the title indole derivative, C22H21NO4, the dihedral angle between the benzene and pyrrole rings of indole moiety is 1.8 (1)°. The plane of the 4-meth-oxy-phenyl ring is oriented with a dihedral angle of 60.7 (1)° with respect to the plane of the indole moiety. The mol-ecular packing is stabilized by C-H⋯O hydrogen bonds which form a V-shaped chain arrangement along the bc plane of the unit ...

In the unsymmetrical title complex, [Ni(C(20)H(23)N(4)O(4))]ClO(4), the coordination geometry for the Ni(II) atom can be described as square planar. The aromatic rings in the two ligands are almost vertical, with a dihedral angle of 85.3°. In the crystal, cations and anions are linked by weak C(N)-H⋯O hydrogen bonding.
