چکیده
The title compound, C(16)H(14)N(6)O, was prepared by the condensation of 4-(trifluoro-meth-yl)phenol and sodium pyrazol-1-ide in a yield of 58%. The dihedral angles formed by the planes of the pyrazole rings are 50.7 (2), 71.2 (3) and 95.8 (2)°. The mol-ecules are associated into dimers by pairs of inter-molecular O-H⋯N hydrogen bonds involving the hy-droxy groups and pyrazole N atoms. In addition, π-π stacking between the phenol rings of these inversion-related dimers is observed, with a ring centroid-to-centroid distance of 3.9247 (10) Å.

In the title salt, [Na(C(16)H(22)N(6))(2)]CF(3)SO(3), the Na(+) cation is coordinated by six N atoms from two tridentate tris-(3,5-dimethyl-pyrazol-1-yl)methane ligands in a distorted octa-hedral geometry. The Na-N distances range from 2.427 (3) to 2.507 (3) Å, intra-ligand N-Na-N angles range from 74.71 (8) to 79.31 (9)°, and adjacent inter-ligand N-Na-N angles range between 100.42 (9) and 104...

In the title compound C27H22Cl2N4O2, the pyrazol-5-ol ring makes a dihedral angle of 34.80 (11)° with the phenyl ring to which it is bound, while the pyrazolone ring is inclined at 34.34 (12)° to its attached phenyl ring. In the crystal, N-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules into chains along [010]. Inter-molecular π-π inter-actions are observed between the pyrazolone ring and the...

The title zinc complex, [ZnCl(2)(C(18)H(22)N(4))], contains a bidentate 1,2-bis(3,5-dimethyl-1H-pyrazol-1-ylmeth-yl)benz-ene ligand that binds to the zinc atom, forming a nine-membered metallocyclic ring. The geometry about the Zn atom is distorted tetra-hedral, with the largest deviation observed in the magnitude of the Cl-Zn-Cl angle. Similar distortions are observed in the cobalt analogue an...
