Dipyridin-2-ylamine (0.031 g, 0.016 mmol), crotonictic acid (0.028 g, 0.032 mmol), Ni(CH3COO)2 (0.18 g, 0.018 mmol) and NaOH (0.048 g, 0.12 mmol), were added to a mixed solvent of ethanol and acetonitrile. The mixture was heated for five hours under reflux with stirring. The resultant filtrate was infiltrated with diethyl ether in a closed vessel, and green blocks of (I) grew after one week.
The C-bound H atoms were located in difference maps and freely refined. The O– and N-bound H atoms were located in difference maps and refined with O—H = 0.86 (1)Å and N—H = 0.88 (1) Å, respectively.
The molecular title complex, (I), complements related materials (Yang et al., 1997).
As shown in Fig. 1, the Ni(II) ion in (I) is coordinated by two N atoms of one chelating dipyridin-2-ylamine ligand, two O atoms of monodentate crotonictate anions and one O atom of a water molecule, forming a square-pyramidal coordination environment (Table 1). The N atoms occupy sites in the basal plane and the water molecule occupies the apical site.
A network of O—H···O and N—H···O hydrogen bonds helps to stabilize the packing (Table 2).

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 molecular title complex, (I), complements related materials (Yang et al., 1997).
As shown in Fig. 1, the Ni(II) ion in (I) is coordinated by two N atoms of one chelating dipyridin-2-ylamine ligand, two O atoms of monodentate crotonictate anions and one O atom of a water molecule, forming a square-pyramidal coordination environment (Table 1). The N atoms occupy sites in the basal plane and the water molecule occupies the apical site.
A network of O—H···O and N—H···O hydrogen bonds helps to stabilize the packing (Table 2).
