5-Amino-1-phenyl-3-trifluoromethyl-1H-pyrazole-4-carboxylic acid

Abstract top

In the title compound, C11H8F3N3O2, there are two molecules in the asymmetric unit wherein the phenyl rings make dihedral angles of 65.3 (2) and 85.6 (2)° with the pyrazole rings. In the crystal, pairs of molecules are held together by O-H...O hydrogen bonds between the carboxyl groups, forming a centrosymmetric dimer with an R22(8) motif. Intramolecular N-H...O interactions are also present.

Comment top

We report here the structure of the title compound (I), isolated during attempts to synthesize Ti(C5H5)2(C11H7F3N3O2)2. In the title compound C11H8F3N3O2, there are two molecules in the asymmetric unit that differ in the dihedral angle formed between the phenyl and pyrazole rings, 65.3 (2) and 85.6 (2)°. The pairs of molecules are held together by O—H···O hydrogen bonds between the carboxyl groups, forming a centrosymmetric dimer with an R22 (8) motif, Fig. 2. (Bernstein et al., 1995) . Related compounds of this ligand show antiproliferative and apoptotic effects against K562, K562-R (imatinib mesilate resistant), HL60 and multidrug resistant HL60 cell lines (Maggio et al., 2008).

Experimental top

The synthesis of title compound has been described by Maggio et al., 2008. The title compound was reacted with titanocene dichloride, (C5H5)2TiCl2. Elemental analysis {C, 53.50, H, 3.37, N, 11.70%. Found: C, 53.66, H, 3.45, N, 11.54%} indicated formation of Cp2Ti(ligand)2,= Ti(C5H5)2(C11H7F3N3O2)2, ligand = 5-amino-1-phenyl-3- (trifluoromethyl)-1H-pyrazole-4-carboxylate. Melting point 190–195°C. IR(nujol, cm-1): 3439w, 3332w (N—H), 3049w (Carom-H), 1661 s, 1611 s (COO), 1537 s, 1486 s (C=N + C=C). 1H NMR (CDCl3): 5.59br (10H, Ti—C5H5), 6.40br, 6.60br (6H, –NH2), 7.55 mbr (10H, Carom-H). Good solubility in chloroform, methanol, dimethylsulfoxide; lower solubilty in acetonitrile; insoluble in water. Upon recrystallization flat needles were obtained, they were studied to determine its crystal and molecular structure and revealed only the ligand. Ligand cleavage is a non unusual feature for Ti complexes that show a marked tendency to evolve towards titanium dioxide (Caruso & Rossi, 2004). The title compound synthesis has been described (Maggio et al.). Related compounds of this ligand show antiproliferative and apoptotic effects against K562, K562—R (imatinib mesilate resistant), HL60 and multidrug resistant HL60 cell lines (Maggio et al., 2008).

Refinement top

H atoms bonded to C atoms were located from difference maps and treated as riding model, with C—H distance of 0.95 Å and with Uiso(H) = 1.2Ueq(C). O and N-bound H atoms were freely refined, giving distances and Uiso in the ranges O-H = [ 0.91 (4)-0.94 (4) ]Å, N-H = [0.85 (4)-0.95 (4)] Å and Uiso(H) = [0.067 (12)-0.076 (14)] Å2 Ueq(O) and Uiso(H) = [0.041 (9)-0.066 (12)] Å2 Ueq(N).

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
