The crystal structure shows that the title compound, [Ni₂(CH₃CO₂)(C₂₇H₂₄Cl₃N₄O₃)(CH₄O)₂]·CH₃OH·H₂O, contains [Ni₂L(OAc)(CH₃OH)₂] molecules in the unit cell {H₃L = 5-chloro-2-{1,3-bis[2-(5-chloro-2-oxidobenzylideneimino)-ethyl]imidazolidin-2-yl}phenolate} with water and methanol as solvates. The title compound is a neutral dinuclear compound, in which the L³⁻ Schiff base acts as a heptadentate ligand, using each one of its N₂O compartments to coordinate a nickel atom. The acetate anion bridges the two nickel atoms via one O while the distorted octahedral coordination sphere for each nickel atom is completed by a coordinated methanol ligand. One of the coordinated methanol ligands is involved in an intramolecular hydrogen bond to the uncoordinated O atom of the bridging acetate ligand while the other forms a hydrogen bond with the methanol solvate. The solvate water molecule forms strong hydrogen bonds to both terminal phenolato O atoms. The methanol solvate molecule also forms a hydrogen bond with the water solvate molecule.

Comment top

Nickel complexes of the compartmental triprotic heptadentate ligand, 2-hydroxyphenyl)-1,3-bis[4-(2- hydroxyphenyl)-3-azabut- 3-enyl]-1,3-imidazolidine and its derivatives have been of interest for their ability to give rise to dinuclear compounds with a predefined ground state (Fondo et al., 2005, 2007, 2009; Fondo, Garcia-Deibe et al., 2006; Fondo, Ocampo et al., 2006; Lu et al., 2007; Paital, et al., 2007, 2009). Density functional theory (DFT) calculations demonstrated that the Schiff base provides an NCN bridge between the metal ions that helps to mediate the ferromagnetic exchange (Fondo, et al., 2005). Consequently, the use of suitable cross-linking ligands between the dinuclear units could be a route to produce complexes of higher nuclearity, with all of the unpaired electrons aligned parallel to each other. The type of complex obtained depends on the synthesis conditions as the coordination environment about the metals is usually completed by coordinating solvent molecules.

The crystal structure shows that C₃₂H₄₁Cl₃N₄Ni₂O₉, (I), contains [Ni₂L(OAc)(CH₃OH)₂] molecules in the unit cell (H₃L = 2-(5-chloro-2-hydroxyphenyl)-1,3-bis[4-(5-chloro-2- hydroxyphenyl)-3-azabut-3-enyl]-1,3-imidazolidine) with water and methanol as solvates. (I) is a neutral dinuclear compound, where the L^3- Schiff base acts as a compartmental trianionic heptadentate ligand, using each one of its N₂O compartments to coordinate a nickel atom. Thus, the metal atoms are joined to one terminal phenol oxygen (O1A, O1B), an iminic nitrogen (N1A, N1B), and an aminic nitrogen atom (N2A, N2B), with the aminic NCN group (N2A—C7—N2B) acting as a bridge between both nickel ions. In addition, the nickel centers are linked by the endogenous phenolate oxygen atom (O1) of the central ligand arm and by an exogenous bridging monodentate acetate group (O1AA). This gives rise to a nearly planar Ni₂O₂ metallacycle, with an intramolecular Ni—Ni distance of 3.1078 (6) Å. The coordination spheres of the nickel atoms are completed by methanol molecules. Therefore, the metal centers are hexacoordinated in a N₂O₄ environment, with an octahedral geometry. The Ni—O and Ni—N distances, as well as the angles about the metal atoms, show quite regular polyhedra around the central ions, with both the Ni—O_phenol—Ni and Ni—O_acetate—Ni angles being similar [97.98 (7)° and 97.37 (8)°, respectively]. There are similar structures reported in the literature which differ only in the nature of the coordinating solvent (H₂O) and solvate molecules (H₂O, CH₃CN) in the lattice (Fondo, Ocampo et al., 2006).

One of the coordinated methanol ligands is involved in an intramolecular hydrogen bond to the uncoordinated O atom (O2AA) of the bridging acetate ligand while the other forms a hydrogen bond with the methanol solvate. The solvate water molecule forms strong hydrogen bonds to both O1A and O1B. The methanol solvate molecule also forms a hydrogen bond with the water solvate molecule.

Experimental top

For the synthesis of the ligand (H₃L) methanol solutions of triethylenetetramine and 5-chlorosalicylaldehyde were mixed in 1:3 mol ratio. After heating at 60° C for a few minutes, ether was added to this mixture, and the yellow crystals were separated, filtered and recrystallized from methanol solution. Mp 103–104° C. For synthesis of the complex, to a stirred methanol solution (25 ml) of [Ni(O₂CCH₃)₂]4H₂O (1.5 g, 2.67 mmol) was added 1.33 g (5.35 mmol) of the ligand H₃L. Slow evaporation of the green filtrate overnight yielded green cystals suitable for X-ray analysis in 75% yield.

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 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.
