Source of material

The salicylaldimine compound was synthesized and obtained in good yields from a 2:1 reaction ratio of substituted salicylaldehyde 2-hydroxy-5-methylbenzaldehyde with 1,3-diaminopropane in dry methanol under reflux. The compound was obtained as a yellow solid with yields of 96%.

Experimental details

Single crystals suitable for X-ray diffraction (XRD) studies for the compound were obtained after four weeks by slow diffusion and evaporation of hexane into a concentrated solution of the compound in dichloromethane (DCM). Crystal evaluation and data collection were done on a Bruker Smart APEX2 diffractometer [1] Crystal evaluation and data collection were done on a Bruker SMART 1000 CCD diffractometer with Mo Kα radiation (λ = 0.71073 Å) equipped with an Oxford Cryostream low temperature apparatus operating at 100(1) K. The structure was solved by direct method using the SHELXS [2] program and refined with SHELXL [3].

All hydrogen atoms were placed in idealized positions and refined in riding models with U iso assigned the values of 1.2 times or 1.5 times those of their parent atoms and the distances of C–H were constrained to 0.95 Å for all the aromatic H atoms, 0.98 Å for the CH3 protons and 0.9 for CH2 protons or 0.84 Å for the hydroxy group H atoms, respectively. The idealized tetrahedral OH refined as rotating group. The visual crystal structure information was performed using Diamond [4].

Comment

N,O-salicylaldimines are Schiff base ligands with the ability to coordinate transition metal ions via the hard nitrogen and oxygen donor atoms. This leads to a stabilization of the metal complexes against reduction and eventually give good thermal stability [5]. It is also easy to manipulate their steric and electronic properties. The early transition metal complexes have been shown to exhibit high oxophilic nature [6, 7]. Despite this shortcoming, a lot of research has been conducted on salicylaldimine complexes and their application as catalysts in polymerization reactions. For instance, group four metal-complexes of titanium and zirconium have been synthesized and tested, which showed significant (co)polymerization of ethylene [8], [9], [10]. Their salicylaldimine complexes have also been shown to exhibit stability, catalytic activity and greater tolerance for polar monomers in olefin polymerization [11].

The asymmetric unit of the title compound contains one salicylaldimine molecule. In the structure, the 2-(iminomethyl)-4-methylphenol moieties are on either sides of the propyl linker and enclose a dihedral angle of 52.40(3) comparable to that of in the structure of 4,4′-Dichloro-2,2′- [(1E,1′E)-propane-1,3-diylbis(nitrilomethylidyne)]diphenol [12].

In the crystal, this compound displays two intramolecular hydrogen bonds O–H⃛N with an N⃛O distance of 2.593(2) Å. The bond distances and angles are comparable to those of related compounds [13], [14], [15], [16].
