The address of one of the authors in the paper by Subhadramma et al. [Acta Cryst. (2015), E71, o455-o456] is corrected.[This corrects the article DOI: 10.1107/S2056989015010488.].
All the non-H atoms of the title compound, C(10)H(10)N(2)O(2), are nearly in the same plane with a maximum deviation of 0.093 (1) Å. In the crystal, adjacent mol-ecules are linked by pairs of inter-molecular N-H⋯O hydrogen bonds, generating inversion dimers with R(2) (2)(14) ring motifs.
The crystal structures of two title Schiff base derivatives, C15H12N4O·C2H6O (1·EtOH) and C13H13N3O2S (2), were determined at 110 and 100 K, respectively. In the crystal of compound 1·EtOH, the (E)-N'-[(1H-indol-3-yl)methyl-idene]isonicotinohydrazide and ethanol mol-ecules are linked by O-H⋯O, N-H⋯O and N-H⋯N hydrogen bonds, forming a tape structure running… (More)
In the title compound, C(22)H(23)N(3)O(2)S(2), the five-membered ring is planar and the C(5)S ring adopts a chair conformation. The crystal packing is stabilized by inter-molecular N-H⋯O and C-H⋯O inter-actions, generating a chain and a centrosymmetric dimer, respectively.
There are two independent mol-ecules in the asymmetric unit of the title compound, C(10)H(9)NO(3), in both of which, all non-H atoms except for the methyl C atom lie nearly in the same plane [maximum deviations = 0.094 (3) and 0.043 (2) Å]. In the crystal, each independent mol-ecules is linked by pairs of C-H⋯O inter-actions, generating inversion dimers… (More)
The title compound, C(28)H(21)N(3)S, crystallizes with two mol-ecules in the asymmetric unit. There are only very slight differences in the torsion angles between the two molecules. The two mol-ecules are stabilized by intra-molecular N-H⋯N inter-actions and the crystal packing is stabilized by inter-molecular N-H⋯S inter-actions.
In the title compound, C15H11N3O4, the acetamide group is inclined to the furan ring by 66.5 (1)°. The dihedral angle between the furan ring and the benzene ring is 66.8 (1)°. In the crystal, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds, forming inversion dimers with an R 2 (2)(12) ring motif. The dimers are linked via two pairs of C-H⋯O hydrogen… (More)
In the title compound, C(8)H(8)N(4), the dihedral angle between the tetra-zole and benzene rings is 21.6 (1)°. An inter-molecular C-H⋯π inter-action is observed.
In the title compound, C(27)H(32)N(2)O(5), the morpholine ring adopts a chair conformation with two C atoms deviating by -0.656 (4) and 0.679 (3) Å from the least-squares plane defined by the rest of atoms in the ring. The tetra-hydro-pyridine ring adopts a half-chair conformation. The mol-ecular structure is stabilized by a strong intra-molecular O-H⋯O… (More)
In the title compound, C(21)H(24)N(2)O(3)S(2), the three five-membered rings adopt envelope conformations. The dihedral angle between the two aromatic rings is 68.4 (1)°. C-H⋯O inter-actions link the mol-ecules into a chain and the chains are cross-linked via C-H⋯π inter-actions involving the meth-oxy-phenyl ring.
