In the title compound, [Zn(NO3)2(C12H12N2)(H2O)], the ZnII atom is six-coordinated in a distorted octahedral geometry by two N atoms from a chelating 4,4′-dimethyl-2,2′-bipyridine ligand, one water O atom, one O atom from a monodentate nitrate anion and two O atoms from a chelating nitrate anion. In the crystal, there are aromatic π–π contacts between the pyridine rings [centroid–centroid distances = 3.9577 (13) Å] and intermolecular O—H⋯O and C—H⋯O hydrogen bonds.

For the preparation of the title compound, a solution of 4,4'-dimethyl-2,2'-bipyridine (0.20 g, 1.10 mmol) in methanol (10 ml) was added to a solution of Zn(NO3)2.6H2O (0.33 g, 1.10 mmol) in acetonitrile (10 ml) and the resulting colorless solution was stirred for 20 min at 313 K. This solution was left to evaporate slowly at room temperature. After one week, colorless prismatic crystals of the title compound were isolated (yield 0.33 g, 76.6%).
H atoms bonded to C were positioned geometrically, with C—H=0.93Å for aromatics H and constrained to ride on their parent atoms, with Uiso(H)=1.2Ueq. H atoms bonded to O were freely refined.
4,4'-Dimethyl-2,2'-bipyridine (4,4'-dmbipy), is a good bidentate ligand, and numerous complexes with 4,4'-dmbipy have been prepared, such as that of mercury (Kalateh et al., 2008; Yousefi et al., 2008), indium (Ahmadi et al., 2008), iron (Amani et al., 2009), platin (Hojjat Kashani et al., 2008), manganese (Sakamoto et al., 2004), silver (Bellusci et al., 2008), gallium (Sofetis et al., 2006), copper (Willett et al., 2001), iridium (Yoshikawa et al., 2003), cadmium (Kalateh et al., 2010) and zinc (Alizadeh et al., 2010). Here, we report the synthesis and structure of the title compound.
In the molecule of the title compound, (Fig. 1), the ZnII atom is six-coordinated in a distorted octahedral configurations by two N atoms from the chelating 4,4'-dimethyl-2,2'-bipyridine, one O atom from water, one O atom from mono dentate nitrate anion and two O atoms from the chelating nitrate anion. The Zn—O and Zn—N bond lengths and angles are collected in Table 1.
In the π-π contacts between the pyridine rings, Cg3···Cg4i [symmetry cods: (i) 1-X,-Y,-Z, where Cg3 and Cg4 are centroids of the rings (N1/C1—C3/C5—C6) and (N2/C7—C9/C11—C12), respectively] further stabilize the structure, with centroid-centroid distances of 3.9577 (13) Å.
intermolecular O—H···O and C—H···O hydrogen bonds (Table 2 & Fig. 2) link the molecules, in which they may be effective in the stabilization of the structure. There are also aromaticFor related structures, see: Ahmadi et al. (2008); Alizadeh et al. (2010); Amani et al. (2009); Bellusci et al. (2008); Hojjat Kashani et al. (2008); Kalateh et al.

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. |

4,4'-Dimethyl-2,2'-bipyridine (4,4'-dmbipy), is a good bidentate ligand, and numerous complexes with 4,4'-dmbipy have been prepared, such as that of mercury (Kalateh et al., 2008; Yousefi et al., 2008), indium (Ahmadi et al., 2008), iron (Amani et al., 2009), platin (Hojjat Kashani et al., 2008), manganese (Sakamoto et al., 2004), silver (Bellusci et al., 2008), gallium (Sofetis et al., 2006), copper (Willett et al., 2001), iridium (Yoshikawa et al., 2003), cadmium (Kalateh et al., 2010) and zinc (Alizadeh et al., 2010). Here, we report the synthesis and structure of the title compound.
In the molecule of the title compound, (Fig. 1), the ZnII atom is six-coordinated in a distorted octahedral configurations by two N atoms from the chelating 4,4'-dimethyl-2,2'-bipyridine, one O atom from water, one O atom from mono dentate nitrate anion and two O atoms from the chelating nitrate anion. The Zn—O and Zn—N bond lengths and angles are collected in Table 1.
In the crystal structure, intermolecular O—H···O and C—H···O hydrogen bonds (Table 2 & Fig. 2) link the molecules, in which they may be effective in the stabilization of the structure. There are also aromatic π-π contacts between the pyridine rings, Cg3···Cg4i [symmetry cods: (i) 1-X,-Y,-Z, where Cg3 and Cg4 are centroids of the rings (N1/C1—C3/C5—C6) and (N2/C7—C9/C11—C12), respectively] further stabilize the structure, with centroid-centroid distances of 3.9577 (13) Å.
