The asymmetric unit of the title complex, [Pd(C₁₉H₂₀N₂O₂)]·0.5C₂H₅OH, contains two molecules of a Pd^II complex of a Schiff base ligand with an N₂O₂ donor set and one ethanol molecule. The Pd^II centers are in distorted square-planar geometries with the N₂O₂ donor atoms of the tetradentate Schiff base dianions. The ethanol molecule takes part in an O—H⋯O hydrogen bond. In the crystal structure, molecules are stacked approximately along the b-axis direction. The O atom and three H atoms of the solvent molecule are disordered over two positions; the site occupancy factors are ca 0.8 and 0.2.

Comment top

In the field of coordination chemistry, the unique properties of Schiff bases as chelating ligands have attracted significant attention (Caselli et al., 2005; Pou et al., 2007; Ramírez et al., 2008; Roy et al., 2008). Their complexes with palladium(II) ions are found to be efficient catalysts in organic synthesis, especially in C—C bond formation (Abu-Surrah et al., 1999; Ayala et al., 2004; Lai et al., 2005). In the present paper, the preparation and crystal structure of the complex N,N'-bis-salicylidene-2,2-dimethylpropane-1,3-diamine palladium(II) is described.

The asymmetric unit of the title complex (Fig. 1) contains two molecules of the Pd^II complex (A and B) of the Schiff base ligand and one solvated ethanol molecule. The ethanol molecule shows disorder. The Pd^II ion in both A and B has a distorted square-planar environment in which the ligand is coordinated to the Pd^II ion as a tetradentate chelating ligand via the two phenolic oxygen atoms and two imine nitrogen atoms, yielding three six-membered rings. In A, two rings are essentially planar (Pd1A/N1A/C2A/C3A/C8A/O1A and Pd1A/N2A/C9A/C14A/C15A/O2A) and one adopts a half-chair conformation; Pd1A/N1A/C1A/C17A/C16A/N2A with atom C17A displaced from the Pd1A/N1A/C1A/C16A/N2A plane by 0.425 (4) Å and with Cremer & Pople (1975) puckering parameters: Q = 0.573 (4) Å, θ = 126.0 (3)° and ϕ = 11.1 (5)°. In B, one ring is essentially planar (Pd1B/N1B/C2B/C3B/C8B/O1B) and two rings have half-chair conformations; Pd1B/N1B/C1B/C17B/C16B/N2B with atom C17B displaced from the Pd1B/N1B/C1B/C16B/N2B plane by -0.443 (4) Å and with Cremer & Pople (1975) puckering parameters: Q = 0.618 (5) Å, θ = 115.8 (4)° and ϕ = 340.2 (5)°; Pd1B/N2B/C9B/C14B/C15B/O2B with atom O2B deviated from the Pd1B/N2B/C9B/C14B/C15B plane by -0.125 (4) Å and with Cremer & Pople (1975) puckering parameters: Q = 0.199 (5) Å, θ = 62.9 (14)° and ϕ = 24.4 (17)°. The Pd^II ions are coordinated in a cis-planar fashion by the two phenolic oxygen atoms and two imine nitrogen atoms. The Pd—O distances are in the range 1.979 (3)–2.008 (4) Å with Pd—N distances 1.981 (3)–2.014 (3) Å, which are typical of the square-planar Pd^II complexes of Schiff base ligands (Adrian et al., 2008). The bond angles around Pd^II ions indicate that the complex has a distorted square-planar geometry as indicated by the angles O—Pd—O in the range 79.66 (11)–80.54 (16)°, O—Pd—N in the range 92.14 (13)–92.95 (11)° and N—Pd—N in the range 94.92 (12)–94.95 (15)°, deviating substantially from that expected for a regular square-planar geometry. The distortion can be attributed to the restricted bite angle of the Schiff base ligand. Other bond lengths and angles observed in the structure are normal (Allen et al., 1987). The dihedral angles between the two phenolate rings [(C3–C8) and (C9–C14)] of the tetradentate Schiff base ligand are 8.3 (2)° in A and 18.5 (3)° in B.

In the crystal packing (Fig. 2), the neighbouring complex molecules are stacked approximately along the b direction by π···π interactions between the Pd1A/N1A/C2A/C3A/C8A/O1A and Pd1B/N1B/C2B/C3B/C8B/O1B rings with the Cg···Cg distance of 3.5724 (19) Å. The crystal is stabilized by O—H···O hydrogen bonds involving the solvated ethanol molecule (Table 1).

Experimental top

The title complex was synthesized by dissolving the N,N'-bis-salicylidene-2,2-dimethylpropane-1,3-diamine ligand (0.9313 g, 3 mmol) in dry ethanol (10 ml). Palladium(II) acetate (0.6735 g, 3 mmol) was then added to the resulting solution and refluxed under nitrogen atmosphere for 5 hr. An orange solid was obtained and washed with cold acetonitrile. Yellow single crystals suitable for X-ray structure determination were obtained by recrystallization from a mixture of chloroform/hexane (1:1 v/v) by slow evaporation of the solvent at room temperature over several weeks. Yield: 80%, M.p. 608.1–608.6 K.

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.
