2-[(E)-(Pyridin-2-ylmethylidene)amino]thiophene-3-carbonitrile
In the title compound, C11H7N3S, the thio-phene and pyridine rings are coplanar, forming a dihedral angle of 3.89 (7)°. The conformation about the C=N bond [1.2795 (18) Å] is E. In the crystal, translationally related mol-ecules along the a axis form weak π-π inter-actions [centroid-centroid distance = 3.8451 (8) Å] between the thio-phene rings.

The asymmetric unit of the title 1:2 adduct, C(12)H(10)N(4)·2C(8)H(8)O(2), comprises a single mol-ecule of 2-phenyl-acetic acid and half a mol-ecule of 3-pyridine-aldazine; the latter is completed by crystallographic inversion symmetry. In the crystal, mol-ecules are connected into a three-component aggregate via O-H⋯N hydrogen bonds. As the carboxyl group lies above the plane through the benze...

In the title compound, C24H20N6O, the pyridin-3-yl groups on the ethyl-ene fragment are found in a trans conformation with a C(py)-C(e)-C(e)-C(py) (py = pyridine, e = ethylene) torsion angle of 179.2 (3)°. The dihedral angle between the pyridine rings is 3.5 (1)°. In the crystal, N-H⋯N and C-H⋯O=C inter-actions form a layer arrangement parallel to the bc plane. The compound displays disorder of...

In the title coumarin derivative, C28H26N2O2, the coumarin unit is approximately planar, with a maximum deviation of 0.048 (3) Å. The central benzene ring is oriented at dihedral angles of 30.15 (14) and 10.51 (11)°, respectively, to the pyridine ring and coumarin ring system. In the crystal, weak C-H⋯O and C-H⋯N hydrogen bonds and weak C-H⋯π inter-actions link the mol-ecules into a three-dimen...
