The title compound, C(6)H(8)N(6), crystallizes as an N-H⋯N hydrogen-bond-linked dimer of two almost identical mol-ecules in the asymmetric unit. Both of the mol-ecules are almost planar (rms deviations of 0.0186 and 0.0296 Å in the two molecules) and their hydrazino groups are turned towards the pyrazole rings. The dimers are arranged into chains via inter-molecular N-H⋯N hydrogen bonds between...

A series of novel 2-substituted hydrazino-6-fluoro-1,3-benzothiazole derivatives were synthesized by synthesizing the 2-hydrazino-6-fluorobenzothiazole and refluxing of this with different substituted acetophenones. The synthesized compounds were evaluated for their possible antimicrobial activity. The structures of few representative compounds were elucidated by IR and NMR. For present work ef...

The title compound, 2C(17)H(13)F(3)N(3)O(+)·SO(4) (2-)·2H(2)O, crystallizes with four independent cations (A, B, C and D) in the asymmetric unit, which is composed of two groups of two cations, one anion and two water mol-ecules (Z' = 2). The dihedral angle between the mean planes of the 4-hydroxy-phenyl and quinolinium groups is 8.9 (7)° in A, 30.1 (6)° in B, 28.8 (8)° in C and 12.8 (1)° in D....

The title compounds 6aâj, 2-[(6-methyl-1,3-benzothiazol-2-yl)amino]-N-[2-(substituted phenyl/furan-2-yl)-4-oxo-1,3-thiazolidin-3-yl]nicotinamides, were prepared from 2-chloropyridine-3-carboxylic acid (1) and 2-amino-6-methyl-benzothiazole (2) by known methods. All the compounds have been established by IR, (1)H NMR, (13)C NMR and elemental analyses. The in vitro antimicrobial screening of the ...

Isatin (3a), isatin 3-carbohydrazone (4a), 5-spiro (isatin) 2-(N-acetyl hydrazino) 4-(N-acetyl)-∆2-1,3,4 oxadiazoline (5a), and 5-spiro (isatin) 2-hydrazino∆2-1,3,4 oxadiazoline (6a) had been synthesized from the unsubstituted oximinoacetanilide (2a). 4-Chlorooximinoacetanilide (2b), 5-chloroisatin (3b), 5-chloroisatin 3-carbohydrazone (4b) and 5-spiro (5-chloroisatin) 2-(N-acetyl hydrazino) 4...

Coordination complexes (1–4) of 2-amino-4-methylbenzothiazole and 2-amino-3-methylpyridine with Cu(CH3COO)2 AgNO3 were prepared characterized by UV/Vis FT-IR spectroscopy. The molecular structure for single crystals silver (2 4) determined X-ray diffraction. coordination complex (2) is monoclinic space group P21/c, wherein two ligands are coordinated to a metal ion, affording distorted trigonal...

The title compound, C(19)H(28)N(8)O(2), was prepared by the reaction of N(2),N(2),N(4),N(4)-tetra-ethyl-6-hydrazino-1,3,5-triazine-2,4-diamine and 1-(4-nitro-phen-yl)ethanone in ethanol at room temperature. The mol-ecular conformation is stabilized by intra-molecular C-H⋯N hydrogen-bonding inter-actions. There are also inter-molecular N-H⋯O hydrogen bonds, and C-H⋯π and π-π inter-actions, which...
