The title compound, [Ni(C5H7O2)2(C5H5N)2]·2H2O, crystallizes with two half-mol­ecules in the asymmetric unit. The NiII ion of each unique complex mol­ecule lies on an inversion centre and has an octa­hedral coordination geometry. The crystal structure features weak O—H⋯O hydrogen bonds, which form chains running parallel to the a axis.

Comment top

The crystal structure of the title compound Ni(acac)2(py)2.2H2O, where acac = acetylacetonate and py = pyridine, is composed of two crystallographically independent Ni complexes with similar geometry and with the Ni(II) atoms located on inversion centres as well as two water molecules located on general positions (Fig. 1). Both Ni(II) atoms have octahedral coordination geometry with the basal plane defined by the four oxygen atoms of the chelating acac (O1, O1i, O2, O2i) and (O3, O3ii, O4, O4ii) for Ni1 and Ni2 respectively, the axial positions are occupied by pyridine N atoms. Related structures have been reported previously in literature: the structure published by Elder (1968) is the anhydrate of the title compound, Zukerman-Schpector et al. (2007) published a methyl pyridine derivative, and the 3 and 4-cyanopyridine derivatives were also reported by Zukerman-Schpector and co-workers (2000). Other structures have been obtained with derivatives of acac: 1,3-diphenyl-1,3-propanedionato (Soldatov, et al., (2001)) and 4-pyridyltetrathiafulvalene (Wang, et al., (2006)). All the bond lengths and angles are in the normal range (Elder et al., 1968; Zukerman-Schpector et al., 2000; Wang et al., 2006). The two independent units are linked to each other by weak O—H···O hydrogen bonds (see Table 2 for geometric details) which form a one-dimensional chain, running parallel to a as shown in Fig. 2. Another feature in this crystal structure is the presence of C—H···π interactions, which further stabilize the crystal packing. These C—H···π interactions are present between the C—H group of acac and an adjacent pyridine rings with a H···π distance of 3.183 Å (Fig. 2).

Experimental top

An amount of 0.075 g (0.5 mmol) of mercapto succinic acid was dissolved in 2 ml of pyridine and 0,1374 g (0.5 mmol) of nickel(II) acetylacetonate was dissolved in 10 ml methanol. The two solutions were mixed and stirred for 15 min. The resulting solution was allowed to stand at room temperature. After several days X-ray quality blue crystals were obtained. A fragment cut from a larger crystal was used for data collection.

Refinement top

Water hydrogen atoms were tentatively found in the difference density Fourier map and were refined with an isotropic displacement parameter 1.5 that of the adjacent oxygen atom. The O—H distances were restrained to be 0.9 Å within a standard deviation of 0.01 with Uiso(H) = 1.5 Ueq(O) and the H···H contacts were restraint to 1.40 Å with a standard deviation of 0.02. All other Hydrogen atoms were placed in calculated positions with C—H distances of 0.93–0.96 Å for aromatic H atoms with Uiso(H) = 1.2 Ueq(C).

Special details top

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 on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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.
