In the title compound, C9H10ClNO, the non-H atoms, excluding the phenyl group, are almost coplanar (r.m.s. deviation of the non-H atoms = 0.1015 Å). The dihedral angle formed between this plane and the benzene ring is 87.07 (5)°. Weak intermolecular C—H⋯O interactions help to stabilize the packing.
The non-H atoms of the title compound, C9H13NO2, are almost coplanar (r.m.s. deviation = 0.0358 Å). Weak intermolecular N—H⋯O hydrogen bonds link the molecules into zigzag chains along the b axis with graph-set motif C(5). The chains are further linked into a three-dimensional network by C—H⋯O hydrogen bonds and C—H⋯π interactions.
In the title compound, C16H18N2O2, the molecule adopts an E conformation about the C=N double bond. The dihedral angle between the pyrrole and phenyl rings is 41.55 (8)°. In the crystal structure, pairs of intermolecular N—H⋯O hydrogen bonds link the molecules into centrosymmetric dimers. In the dimer, the two pyrrole rings are almost coplanar and the two phenyl rings are parallel to each other.
In the title complex, [CuCl2(C18H16N2O2)2]·CH3CN·H2O, the six-coordinated Cu atom is in a distorted octahedral geometry with the donor centers of two O atoms and two N atom from two bidentate ligands, and two chloride ions. In the crystal, pairs of intermolecular N—H⋯ Cl hydrogen bonds form centrosymmetric dimers and intermolecular O—H⋯ O hydrogen bonds between the ligand and the uncoordinated water molecules link the dimers into chains parallel to the c axis.
In the title complex, [Zn(NO3)2(C17H14N2O2)(H2O)], the six-coordinated Zn atom is in a distorted octahedral geometry, the donor centers being two O atoms and one N atom from the tridentate organic ligand, a water O atom and two O atoms from two monodentate nitrate ions. In the crystal, O—H⋯O hydrogen bonds between the coordinated water molecules and nitrate O atoms and N—H⋯O hydrogen bonds between the main ligand and nitrate O atoms consolidate the three-dimensional network.
In the title compound, C21H24N4O3, the molecule has an E configuration about the imine C=N double bond. Intermolecular N—H⋯O hydrogen bonds assemble molecules into centrosymmetric dimers.
The molecule of the title compound, C10H13NO3, is approximately planar (maximum deviation 0.1424 Å). In the crystal, molecules are linked into inversion dimers by pairs of N—H⋯O hydrogen bonds, and the dimeric units are linked by non-classical C—H⋯O hydrogen bonds, forming a layered structure.
