2-[1-(9-Anthrylmethyl)-1H-pyrazol-3-yl]pyridine

S.-L. Zhang, B.-Y. Xie and D.-B. Qin

Abstract top

The title compound, C23H17N3, can be used in coordination chemistry. The anthracene ring makes dihedral angles of 86.08 (5) and 76.63 (6)°, respectively, with the pyridine and pyrazole rings. The dihedral angle between the pyrazole and pyrimidine rings is 11.79 (7)°. In the structure, weak intermolecular C-H...N hydrogen bonds are observed.

Comment top

In recent years, scientists have paid much attention to the synthetic approach and the structural control of coordination architectures with ligands based on pyrazolyl-pyridine chelating units. (Stell, 2005; Ward et al., 2001). In addition, some pyrazole-derived ligands are useful in medication. (Amir et al., 2008). We report herein the synthesis and crystal structure of the title compound (I). Bond lengths and angles in (I) (Fig. 1) are normal.

The dihedral angles formed by the anthracene ring between pyridine and the pyrazole rings are 86.08 (5)° and 76.63 (6)°, respectively. Pyrazole makes a dihedral angle of 11.79 (7)° with pyridine ring .

Weak intermolecular C—H···N hydrogen bonds between molecules are observed.

Experimental top

The title compound was prepared according to the reported procedure of Amoroso et al. (1994). Yellow single crystals suitable for X-ray diffraction were obtained by recrystallization from dichloromethane and pPetroleum ether.

Refinement top

H atoms were placed in calculated positions with C—H = 0.95–0.9900 Å, and refined in riding mode with Uiso(H) = 1.2Ueq(C).

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.
