نویسندگان
چکیده
The asymmetric unit of the title salt, C3H6N3 (+)·C2F3O2 (-), contains two independent 3-amino-pyrazolium cations and two independent tri-fluoro-acetate anions. The F atoms of both anions were refined as disordered over two sets of sites, with common occupancy ratios of 0.639 (12):0.361 (12). In the crystal, the cations and anions are linked via N-H⋯O hydrogen bonds, forming chains along [100] and [010].

The title solvated salt, C21H17N7 (2+)·SO4 (2-)·CH3OH, was obtained when we attempted to prepare the complex of ferrous sulfate and 2,6-bis-[3-(pyridin-2-yl)-1H-pyrazol-1-yl]pyridine in methanol. The dihedral angles between adjacent pyridine and pyrazole rings range from 3.8 (1) to 13.4 (1)°. An intra-molecular N-H⋯N hydrogen bond occurs. In the crystal, N-H⋯O and O-H⋯N hydrogen bonds between s...

The title compound, (C(4)H(7)N(4)O)(2)[Bi(2)Cl(9)(C(4)H(7)N(4)O)]·H(2)O, was prepared by the reaction of bis-muth trichloride and 5-amino-1H-imidazole-4-carboxamide in a dilute HCl medium. The asymmetric unit contains two 5-amino-4-amino-carbonyl-1H-imidazol-3-ium cations, one edge-shared non-centrosymmetric biocta-hedral [Bi(2)C1(9)(C(4)H(7)N(4)O)](2-) dianion and a water mol-ecule.

4-Aminoantipyrine was utilized as key intermediate for the synthesis of pyrazolone derivatives bearing biologically active moieties. The newly synthesized compounds were characterized by IR, 1H- and 13C-NMR spectral and microanalytical studies. The compounds were screened as anticancer agents against a human tumor breast cancer cell line MCF7, and the results showed that (Z)-4-((3-amino-5-imino...

In the title compound, [Cu(C21H19N6O2)Cl], the Cu(II) atom is in a slightly distorted square-planar coordination involving two O atoms from the pyrazolone rings [Cu-O = 2.088 (10) and 1.975 (10) Å], an N atom of the azo group [Cu-N = 2.048 (13) Å] and a chloride anion [Cu-Cl = 2.183 (5) Å]. The organic anions act as tridentate chelating ligands. The mol-ecules stack in columns along the c axis.
