N, N΄-3, 4-di(methylamino)-1, 2, 5-oxadiazole (1f) was prepared by dehydration of N, N΄-3, 4-di(methylamino)glyoxime (2f) in aqueous potassium hydroxid at 170-180 ˚C. Under similar conditions N, N΄-3, 4-di(benzylamino)-1, 2, 5-oxadiazole (1c) and N, N΄-3, 4-di(isopropylamino)...

In the title compound, C(11)H(15)N(3)O(3), one of the methyl groups attached to the benzamide unit is slightly twisted with a C-N-C-C torsion angle of 4.04 (13)°. The crystal packing is stabilized by weak intermolecular C-H⋯O hydrogen bonds together with a weak C-H⋯π inter-action.

In the title compound, C12H12N2O2, synthesized by ammonolysis of 3-phenyl-isoxazole-5-carbonyl chloride in di-chloro-methane, the dihedral angle between the isoxazole ring and the phenyl ring is 14.05 (7)°. In the crystal, centrosym-metrically related mol-ecules are linked into dimers by pairs of C-H⋯O hydrogen bonds, generating rings of graph-set motif R 2 (2)(10).

We introduce a new 5-valued logic that we call N ′ 5. This logic extends GLukG, a paraconsistent logic recently introduced [10]. We show that N ′ 5 is sound with respect to GLukG.

The title compound, C(26)H(26)N(2)O(4), synthesized by the reaction of naphthalene-1,4,5,8-tetra-carboxylic acid anhydride and cyclo-hexyl-amine, exhibits good n-type semiconducting properties. Accordingly, thin-film transistor devices comprising this compound show n-type behavior with high field-effect electron moblity ca 6 cm(2)/Vs [Shukla, Nelson, Freeman, Rajeswaran, Ahearn, Meyer & Carey(2...

In the title complex, [Cd(C(7)H(4)N(5)O(2))(2)(H(2)O)(2)]·2H(2)O, the water-coordinated Cd(II) atom ( symmetry) is coordinated by four N atoms from two symmetry-related 3-carboxy-pyidyl-6-tetra-zolato ligands, forming a distorted octa-hedral complex. The uncoordinated water mol-ecules connect the mononuclear units into a layer structure through O-H⋯N and O-H⋯O hydrogen bonds; similar hydrogen b...
