In the title compound, [Ni(C11H12N3O3)(CH3CO2)(H2O)2]·C2H5OH, the coordination geometry of the NiII atom is a distorted octahedron, with one carbonyl O and two imino N atoms of the hydrazone ligand, together with an acetate O atom, comprising the basal plane, and the two water O atoms occupying axial positions.

CCDC reference: 144617
Compound (I) was synthesized by the reaction of a 1:1 mole ratio of diacetyl
monoxime salicyloyl hydrazone and nickel(II) acetate tetrahydrate in ethanol
at room temperature. Green single crystals of (I) suitable for X-ray
diffraction were obtained by evaporating the solution in air for several
weeks.

Special details top
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 on F2 for ALL reflections except for 2 with very negative
F2 or 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. |

Salicylhydroxamic acid and analogous derivatives, because of the nature of these polydentate ligands, may function as cation recognition agents to form metallacrown ether compounds (Gibney et al., 1994; Psomas et al., 1998), but salicylic hydrazide, with a similar structure, does not have this function. Compared with salicylic hydrazide, salicyloyl hydrazone Schiff bases have additional donor atoms, whose presence introduces a wider range of properties (Kwak et al., 1998) as new types of the inorganic host molecules. We report here the crystal structure of a new nickel(II) salicyloyl hydrazone complex, (I), derived from salicylic hydrazide.
The coordination geometry of NiII in (I) is a distorted octahedron. The two water molecules occupy the axial positions, while atom O5 of the carbonyl and the two atoms N1 and N2 of the imino in the hydrazone, together with atom O1 of the acetate, comprise the basal plane (mean deviation from the plane 0.0084 Å). The basal plane is stabilized by intramolecular O4—H4A···O2 hydrogen bonds, in which O4 is from the oxime and O2 from the acetate. Atom O6 of the hydrazone ligand and atom O3 of the ethanol molecule do not form coordination bonds but can both link two water molecules from two neighbouring molecules of the complex by strong intermolecular hydrogen bonds of the form O1Wi—H2i···O6, O2Wii—H3ii···O6, O1W—H1···O3 and O2Wiii—H4iii···O3; atom O6 has additional intramolecular hydrogen bonding with N3 (N3—H3A···O6) [symmetry codes: (i) -x - 2, -y, -z; (ii) -x - 3, -y, -z; (iii) x + 1, y, z]. Thus, two rows of complex molecules are connected by these hydrogen bonds to form polymeric chains, which are then connected by O3—H6A···O2iv hydrogen bonds to yield a two-dimensional layer structure (see Fig. 2) [symmetry code: (iv) -x - 1, 1 - y, 1 - z].
