A methanol (12 ml) solution of 2-(3,5-dimethyl-1H-pyrazol-1-yl)-1,10-phenanthroline (0.0544 g, 0.20 mmol) was added to an aqueous (12 ml) solution of CdCl22.5H2O (0.0460 g, 0.20 mmol) and NaNO2 (0.0138 g, 0.20 mmol). The resultant mixture was stirred for a few minutes. The colorless swere 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 and Uiso = 1.5Ueq(C) for methyl-H, and C—H = 0.93 Å and Uiso = 1.2Ueq(C) for the remaining H atoms.
Derivatives of 1,10-phenanthroline play an important role in coordination chemistry and many complexes have been published with these molecules functioning as ligands. To our knowledge, two cadmium complexes with 2-(3,5-dimethyl-1H-pyrazol-1-yl)-1,10-phenanthroline derivative as the ligand have been reported (Wang et al., 2009; Sun et al., 2010). To study the relevance between the coordination geometry with anion, we synthesized the title complex, (I), and herein report its crystal structure.
The molecular structure of (I), Fig. 1, shows the CdII atom is coordinated by three N atoms and four O atoms within a distorted monocapped octahedral coordination geometry. The coordination geometry in (I) contrasts the penta-coordination found in the structures of the related di-chloride and di-thiocyanate derivatives (Wang et al., 2009; Sun et al., 2010). The non-hydrogen atoms of the 2-(3,5-dimethyl-1H-pyrazol-1-yl)-1,10- phenanthroline ligand define an approximate plane with a r.m.s. value = 0.0917 Å; the maximum deviation of 0.2066 (33) Å is found for the C17 atom. The π–π stacking interactions with the closest of these occurring between centrosymmetrically related C4–C8 rings [Cg1···Cg1i = 3.5537 (18) Å for i: 1-x, 2-y, -z].

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 coordination chemistry and many complexes have been published with these molecules functioning as ligands. To our knowledge, two cadmium complexes with 2-(3,5-dimethyl-1H-pyrazol-1-yl)-1,10-phenanthroline derivative as the ligand have been reported (Wang et al., 2009; Sun et al., 2010). To study the relevance between the coordination geometry with anion, we synthesized the title complex, (I), and herein report its crystal structure.
The molecular structure of (I), Fig. 1, shows the CdII atom is coordinated by three N atoms and four O atoms within a distorted monocapped octahedral coordination geometry. The coordination geometry in (I) contrasts the penta-coordination found in the structures of the related di-chloride and di-thiocyanate derivatives (Wang et al., 2009; Sun et al., 2010). The non-hydrogen atoms of the 2-(3,5-dimethyl-1H-pyrazol-1-yl)-1,10- phenanthroline ligand define an approximate plane with a r.m.s. value = 0.0917 Å; the maximum deviation of 0.2066 (33) Å is found for the C17 atom. The crystal structure is stabilised by π–π stacking interactions with the closest of these occurring between centrosymmetrically related C4–C8 rings [Cg1···Cg1i = 3.5537 (18) Å for i: 1-x, 2-y, -z].
