The 2(C12H10N2O2)2], obtained from the reaction of 4-(4-nitrobenzyl)pyridine with zinc(II) iodide, contains two independent discrete distorted tetrahedral complex units [Zn—I = 2.5472 (8)–2.5666 (7) Å and Zn—N = 2.044 (4)–2.052 (4) Å], which are essentially identical conformationally. The crystal used for measurement was a racemic twin.

The title compound was synthesized by heating together under reflux for 10 minutes, 1 mmol of zinc(II) iodide and 2 mmol of 4-(4-nitrobenzyl)pyridine in 50 ml of 50% ethanol–water. After concentration to ca 30 ml, partial room temperature evaporation of the hot-filtered solution gave pale yellow flattened prisms of (I) from which a suitable specimen was cleaved for the X-ray analysis.
Hydrogen atoms were included in the
in calculated positions with C–H = 0.93 Å (aromatic) or 0.97 Å (aliphatic) and allowed to ride, with Uiso(H) = 1.2Ueq(C). A racemic twin was identified and treated as such using the appropriate SHELXL97 function [BASF factor, 0.430 (14)]. Oxygen atoms of the terminal nitro groups were significantly disordered, one in particular (O41C, Uiso = 0.142 Å2) subsequently being refined isotropically.Data collection: CrysAlis PRO (Oxford Diffraction, 2010); cell

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
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. |

The structures of complexes of ZnI2 with pyridine and substituted pyridine ligands, of the type [ZnI2(py)2] are common in the crystallographic literature e.g. with pyridine (Le Querler et al., 1977), and with nicotinamide and isonicotinamide (Pasaoglu et al., 2006). These complexes are usually discrete with distorted tetrahedral stereochemistry. Polymeric complexes having similar stereochemistry are also formed with bifunctional pyridines such as 4,4'-bipyridine (Fan & Wu, 2006). We obtained the title compound [ZnI2(C12H10N2O2)2] (I) from the reaction of zinc(II) iodide with 4-(4-nitrobenzyl)pyridine (L) and the structure is reported here. This substituted pyridine has only occasionally been used as a ligand in metal complex formation e.g. in the mixed-ligand PtII complex with 2,9-diphenyl-1,10-phenanthroline (Chan et al., 1993).
In the structure of (I), the asymmetric unit contains two independent discrete distorted tetrahedral [ZnI2L2] complex units, involving Zn1 and Zn2 (Figs. 1, 2). The Zn—I range is 2.5472 (8)–2.5666 (7) Å, the Zn—N range is 2.044 (4)–2.052 (4) Å and the bond angle range about Zn is 98.99 (17)–119.96 (2)° (for I1—Zn1—I2 and N1A—Zn1—N1B, respectively). The two complex molecules are essentially identical conformationally and are related by pseudo-symmetry, being treated as a racemic twin in the structure refinement.
In the crystal packing of (I) there are only weak intermolecular aromatic C—H···Onitro interactions [C5A—H···O41D, 3.211 (9) Å and C6B—H···O41B, 3.295 Å] but there are some aromatic ring π–π associations involving the C11B–C61B rings: ring centroid separation, 3.591 (3) Å; inter-ring dihedral angle, 3.46 (1)°] (Fig. 3).
