Bis{2-[1-(benzylimino)ethyl]phenolato}palladium(II)

In the title compound, [Pd(C15H14NO)2], the Pd atom lies on an inversion center and is coordinated by two ligand molecules through the O and N atoms in a bidentate manner, forming a slightly distorted square-planar geometry. The dihedral angle between the two benzene rings in the ligand is 76.53 (19)°. The molecular packing is stablized by C—H⋯O and C—H⋯π interactions.

In the title compound, [Pd(C 15 H 14 NO) 2 ], the Pd atom lies on an inversion center and is coordinated by two ligand molecules through the O and N atoms in a bidentate manner, forming a slightly distorted square-planar geometry.

In the title molecule ( Fig. 1), the palladium atom lies on an inversion center and is coordinated to two ligand molecules through the oxygen and nitrogen atoms in a bidentate manner to form a perfect square planar geometry. The bond distances and bond angles in the title complex are normal (Allen et al., 2002). The Pd1-O and Pd1-N bond lengths of 1.981 (2) and 2.039 (2)Å, respectively, in a square planar geometry are typical of square planar Pd(II) of Schiff bases (Adrian et al., 2008). The dihedral angle between the benzene rings is 76.5 (2)°. The molecule is stabilized by C-H..π (C8-H8B···Cg3, C8-H8C···Cg4 and C13H-13 A···Cg3) interactions (Table 1).

Experimental
The ligand, 2-hydroxyacetophenonebenzylimine, (1.1271 g, 5 mmol) was dissolved in hot ethanol (20 ml) in a round-bottomed flask. Palladium(II) acetate (0.5618 g, 2.5 mmol) was dissolved separately in hot ethanol (40 ml) and added into the flask containing the ligand solution. The mixture was stirred and refluxed for 5 h upon which green precipitate was formed.
It was isolated by gravity filtration, washed with cold ethanol and air dried at room temperature. The solid product was recrystallized from chloroform yielding yellow crystals. Yield 87.80%; m.p. 529-530 K.

Refinement
The H atoms were positioned geometrically with C-H = 0.97, 96 and 0.93 Å for methyl, methylene and aromatic groups, respectively, and constrained to ride on their parent atoms with U iso (H) = 1.5(methyl) or 1.2(methylene and aromatic) × U eq (C). The highest peak and deepest hole are located at 0.90 Å from Pd1 atom. Fig. 1. The molecular structure of the title complex with displacement ellipsods drawn at the 50% probability level.
