The title compound, (C13H16N2)[NiCl4] or (H2bpp)·NiCl4 [bpp is 1,3-bis(4-pyridyl)propane], is isostructural with its already reported Cu, Zn and Hg analogues. The structure consists of a doubly charged (H2bpp)2+ cation and a tetrahedral [NiCl4]2− dianion. Both pyridyl N atoms are protonated and form a (H2bpp)2+ cation which adopts an anti–anti conformation with a dihedral angle of 6.287 (7)° between the pyridyl rings. The two pyridyl N atoms are both involved in strong N—H⋯Cl hydrogen bonds, which link both units into a dimer.

NiCl2.6H2O (1.0 mmol, 0.237 g), bpp (1.0 mmol, 0.198 g) and oxydiacetatic acid (1.0 mmol, 0.134 g) were dissolved in 20 ml of methanol-H2O (v/v, 1:3). Then the mixture was sealed in a 25 mL Teflon reactor and kept under autogeneous pressure at 403 K for 5 days. After cooling to room temperature at a rate of 6°C.h-1, blue block shaped crystals suitable for X-ray diffraction were grown from the filtrate by slow evaporation. Yield: 200 mg (50% based on Ni).

H atoms bonded to C and N atoms were positioned geometrically with C—H distance 0.93–0.97Å and N—H distances of 0.8600 Å, and treated as riding atoms, with Uiso(H)=1.2Ueq(C,N).

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. |

The title complex (I) is isostructural with its analogues (H2bpp).CuCl4 and (H2bpp).MCl4.H2O(M = Zn, Hg)(Kao and Chen, 2004), whose structures have been described in detail. The structure consists of a doubly charged (H2bpp)2+ cation and a tetrahedral NiCl42- dianion (Figure 1). Both pyridyl N atoms are protonated and form a (H2bpp)2+ cation, which adopts an anti-anti conformations with a dihedral angle of 6.287° between the two pyridyl rings. The two pyridyl N atoms are both involved in strong N—H···Cl hydrogen bonds (Table 1) and link both units into a dimer (Figure 2).
