The title compound, C(19)H(13)N(5)O(3), can be obtained from the corresponding α-amido-α-amino-nitrone in a reaction with biphenyl-2,2'-diamine. The amido-amidine core has distinctive geometrical parameters including: an outstandingly long Csp(2)-Csp(2) single bond of 1.5276 (13) Å and an amidine N-C-N angle of 130.55 (9)°. Intra-molecular N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds occur. In the cry...

The title neutral copper complex, [Cu(2)Cl(4)(C(8)H(17)N(3)O(2))(2)], shows a binuclear center with a Cu-(μ-Cl)(2)-Cu core, in which each copper ion is coordinated by the N,N,O donor atoms of the tridentate ligand 1,4,6-trimethyl-6-nitro-1,4-diazepine (meaaz-NO(2)) and three chloride exogenous ligands. Each metal ion is facially coordinated by meaaz-NO(2) through N,N,O donor atoms, whereas two ...

The title compound, C11H12N2, is not planar due to the folding of the seven-membered ring. In the crystal, mol-ecules are packed opposite each other to minimize the electronic repulsion but the long inter-molecular distances indicate that no directional contacts are found.

anticonvulsant activity of 7-phenyl-5h-thiazolo[5,4-e][1,2,3,4]tetrazolo[5,1-c]pyrrolo[1,2-a][1,4]diazepine (5) and 7-phenyl-5h-thiazolo[5,4-e][1,3,4]triazolo[5,1-c]pyrrolo[1,2-a][1,4]diazepines (6a-d) was measured against pentylenetetrazole (ptz)-induced seizures in mice. intraperitoneal injections of different doses (12.5, 25 and 50 mg/kg, i.p.) of test compounds decreased ptz-induced seizure...

The organic mol-ecule and uncoordinated water mol-ecule in the crystal of the title compound, C(25)H(24)N(4)O(4)·2H(2)O, both lie on special positions of twofold symmetry. A twofold rotation axis passes through the methyl-ene C atom connecting the two dihydro-benzopyrrolodiazepindionyl parts. The seven-membered C(5)N(2) ring adopts a boat conformation.
