10 ml methanol solution of 2-(3,5-Dimethyl-1H-pyrazol-1-yl)-1,10-phenanthroline (0.0406 g, 0.148 mmol) was added to a 10 ml methanol solution containing Cd(ClO4).6H2O (0.0655 g, 0.156 mmol) and NaNCS (0.0121 g, 0.149 mmol), and the mixed soluton was stirred for a few minutes. The colorless single crystals were obtained after the filtrate had been allowed to stand at room temperature for about a week.
All H atoms were placed in calculated positions and refined as riding with C—H = 0.96 Å, Uiso = 1.5Ueq(C) for methyl H and C—H = 0.93 Å, Uiso = 1.2Ueq(C) for other H atoms.
Derivatives of 1,10-phenanthroline play an important role in modern coordination chemistry and many complexes have been reported with these types of compounds as ligands [see e.g. Liu et al. (2008) for a closely related Cd complex]. To the best of knowledge, no crystal structures of complexes with 2-(3,5-Dimethyl-1H-pyrazol-1-yl)-1,10-phenanthroline as a ligand have been reported so far, and herein we report the
of the title compound (I).The molecular structure of the title compound in shown in Fig. 1. The CdII ion is coordinated by five N atoms in a distorted trigonal bipyramidal environment. Generally, CdII ion assumes six atoms coordination mode and the present five coordination mode may be attributed to the π–π stacking interaction involving the pyrazole ring and a symmetry related pyridine ring with the relevant distances being Cg1···Cg2i = 3.578 (3) Å and Cg1···Cg2iperp = 3.361 Å (symmetry code: (I) -1+x, y, z; Cg1 and Cg2 are the centroids of C7-C10/N3/N6 pyrazol ring and N1/C14/15/C17-C19 pyridine ring, respectively; Cg1···Cg2iperp is the perpendicular distance from Cg1 ring to Cg2i ring).
mode of the ligand 2-(3,5-Dimethyl-1H-pyrazol-1-yl)-1,10-phenanthroline. The non-hydrogen atoms of the 2-(3,5-Dimethyl-1H-pyrazol-1-yl)-1,10-phenanthroline ligand define a plane within 0.0705 Å with a maximum deviation of 0.189 (6) Å for atom C8. In the there is aFor a related structure, see: Liu et al. (2008).

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. |

Derivatives of 1,10-phenanthroline play an important role in modern coordination chemistry and many complexes have been reported with these types of compounds as ligands [see e.g. Liu et al. (2008) for a closely related Cd complex]. To the best of knowledge, no crystal structures of complexes with 2-(3,5-Dimethyl-1H-pyrazol-1-yl)-1,10-phenanthroline as a ligand have been reported so far, and herein we report the crystal structure of the title compound (I).
The molecular structure of the title compound in shown in Fig. 1. The CdII ion is coordinated by five N atoms in a distorted trigonal bipyramidal environment. Generally, CdII ion assumes six atoms coordination mode and the present five coordination mode may be attributed to the chelation mode of the ligand 2-(3,5-Dimethyl-1H-pyrazol-1-yl)-1,10-phenanthroline. The non-hydrogen atoms of the 2-(3,5-Dimethyl-1H-pyrazol-1-yl)-1,10-phenanthroline ligand define a plane within 0.0705 Å with a maximum deviation of 0.189 (6) Å for atom C8. In the crystal structure, there is a π–π stacking interaction involving the pyrazole ring and a symmetry related pyridine ring with the relevant distances being Cg1···Cg2i = 3.578 (3) Å and Cg1···Cg2iperp = 3.361 Å (symmetry code: (I) -1+x, y, z; Cg1 and Cg2 are the centroids of C7-C10/N3/N6 pyrazol ring and N1/C14/15/C17-C19 pyridine ring, respectively; Cg1···Cg2iperp is the perpendicular distance from Cg1 ring to Cg2i ring).
