The title compound, C19H12N2O3, was prepared by the reaction of hydrazine and salicylaldehyde with 1,8-naphthoic anhydride in refluxing dimethylformamide. The structure is stabilized by an intramolecular O—H⋯N hydrogen bond and the crystal packing exhibits C—H⋯O hydrogen bonds. The dihedral angle formed by the benzene and naphthalimide systems is 175.9°. [ABSTRACT FROM AUTHOR]

The structure of the title compound, [Ni(NCS)2(C4H6N2)4], consists of isolated mol­ecules of [Ni(NCS)2(Mim)4] (Mim = 1-methyl­imidazole), which contain a compressed octa­hedral NiN6 chromophore. The NCS− anions are trans and four N atoms from the 1-methyl­imidazole ligands define the equatorial plane. The mean Ni—N(Mim) and Ni—N(NCS) distances are 2.115 (4) and 2.087 (4) Å, respectively.

The title compound, C11H10N6S, was prepared by the reaction of ethyl 2-(1 H-1,2,4-triazol-1-yl)­acetate with hydrazine and phenyl iso­thio­cyanate. The molecular structure and packing are stabilized by an N—H⋯N intermolecular hydrogen-bond and C—H⋯π interactions. [ABSTRACT FROM AUTHOR]

The title compound, C18H18N2O2, was prepared by the reaction of ( E)-1-(4-methoxy­phen­yl)-3-phenyl­prop-2-en-1-one with hydrazine hydrate in acetic acid. The crystal packing is stabilized by weak C—H⋯O hydrogen bonds. [ABSTRACT FROM AUTHOR]

The title compound, [Cu2Cl2(C18H15O3P)4], is a centrosymmetric dinuclear complex, where each CuI atom has a distorted tetra­hedral coordination involving two triphenyl­phosphite ligands and two bridging Cl− anions. The mol­ecular structure and packing are stabilized by C—H⋯O and C—H⋯π inter­actions. [ABSTRACT FROM AUTHOR]

In the title compound, [Co(NCS)2(C4H6N2)2], each cobalt(II) ion is coordinated by two N atoms from two 2-methyl-1 H-imidazole ligands and two N atoms from two iso­thio­cyanate groups. The Co atom lies on a mirror plane and adopts a slightly distorted tetrahedral coordination. The molecular structure and packing are stabilized by intramolecular and intermolecular hydrogen-bond interactions. [ABSTRACT FROM AUTHOR]

In the title compound, [Cd(N3)2(C10H8N2)2], the cadmium(II) ion is coordinated by two N atoms from two azide groups and four N atoms from two 2,2′-bi­pyridine ligands. The coordin­ation geometry of the cadmium(II) ion is distorted octahedral. The packing is stabilized by intermolecular C—H⋯N hydrogen-bond interactions. [ABSTRACT FROM AUTHOR]

In the title compound, C13H11N3OS2, the dihedral angles between the planes of the triazole and phenyl rings and that through the four NC3 atoms of the C=C are 76. (1) and 57.6 (1)°, respectively. There are some intermolec­ular interactions in the crystal structure. [ABSTRACT FROM AUTHOR]

The title compound, C18H14N2O2, was prepared by recrystallization from the fluorescent brightener135. The almost perfectly planar molecule is located on a centre of inversion. The methyl H atoms are disordered equally over two positions. [ABSTRACT FROM AUTHOR]

In the title compound, [Co(C8H8NO2)2], the Co atom has a distorted square-planar coordination involving two N atoms and two O atoms from two ethanone 1-(2-hydroxy­phen­yl)oximato ligands.
