Bis{2-[(E)-(4-fluorobenzyl)iminomethyl]-6-methoxyphenolato}palladium(II)

Abstract

Key indicators: single-crystal X-ray study; T = 100 K; mean (C-C) = 0.002 Å; R factor = 0.029; wR factor = 0.081; data-to-parameter ratio = 31.2.In the title compound, [Pd(C 15 H 13 FNO 2 ) 2 ], the Pd II atom is tetracoordinated by two N atoms and two O atoms from the two 2-[(4-fluorobenzyl)iminomethyl]-6-methoxyphenoxy ligands, forming a square-planar geometry. The two N atoms and the two O atoms around the Pd II atom are trans to each other. The dihedral angle between the two fluoro-substituted benzene rings is 39. 03 (6) . The molecular structure is stabilized by an intramolecular C-HÁ Á ÁO hydrogen bond. In the crystal, weak intermolecular C-HÁ Á Á interactions occur. Related literature

“…The imine N atoms and phenolic O atoms are in mutually trans positions. The Pd-N and Pd-O distances in the N 2 O 2 coordination [1.9741 (10) Å and 2.0204 (12) Å, respectively] are in the same ranges as those observed in the other closely related Pd II complexes of N 2 O 2 Schiff base ligands (Bahron et al, 2011a andHalder et al, 2008). Other bond lengths and angles observed in the structure are also normal (Allen et al, 1987).…”

“…In the title complex (I), [Pd(C 32 H 32 N 2 O 4 )]•(CHCl 3 ), the Schiff base ligand is bis-bidentate (see Fig. 1) and is related to the previously reported bis(2-(1-benzyliminoethyl)phenolato)palladium(II) (Bahron et al, 2011a) but with different substituents on the iminoalkylphenolato and benzyl ring systems. Herein the crystal structure of (I) is reported.…”

“…Six Pd II complexes with related Schiff base N 2 O 2 donor sets have been reported (Brunner et al, 2000;Mehta & Vengurlekar, 2001;Bahron et al, 2011Bahron et al, , 2014Mohd Tajuddin et al, 2012a;Tsuno et al, 2013). However, only three of these Pd II complexes have closely related Schiff base ligands ( Hydrogen-bond geometry (Å , ).…”

“…Indeed, analysis of 2 by single crystal X-ray diffraction studies clearly display the square planar configuration with a typical trans-bis-κ 2 -N,O ligand donor set (τ 4 = 0.00). [14][15][16][17][18][19][20][21][22][23][24] In this Note, we re-examined the synthesis and properties of 2 using a combination of Density Functional Theory (DFT) and spectroscopic techniques (IR, UV-Vis., NMR, etc.). This work demonstrates that the title complex is, in fact, diamagnetic and hence NMR spectra ( 1 H, 13 C, 19 F) of the compound can be measured.…”

This suggests that the presence of a trace of paramagnetic impurity in 2 during spectroscopic identification may be the cause of the unusual observed molecular spin characteristics.…”
