Abstract
Two acridine Schiff base ligand derivatives; 1,1’-(acridine-3,6-diylbis(azaneylylidene))bis(methaneylylidene))bis(naphthalen-2-ol); L1 and N,N’-(acridine-3,6-diyl)bis(1-(quinolin-2-yl)methanimine); L2, were prepared by 1:2 condensation reaction of 3,6-diaminoacridine hydrochloride with 2-hydroxynaphtaldehyde and 2-Quinolinecarboxaldehyde, respectively. Thermal refluxing reactions of group VIB metal carbonyls ((M(CO)6) M= Cr, Mo, and W) with Schiff base ligands resulted in the synthesis of [Cr(L1)(O)2(DMF)](1), [Mo(L1)(O)3(DMF)](2), [W(L1)(O)3(DMF)](3), [Cr(L2)(O)2(DMF)](4), [Mo(L2)(O)3(DMF)](5), and [W(L2)(O)3(DMF)](6).
All formed compounds were characterized by several analytical and spectroscopic analysis such as Elemental analysis, infrared spectroscopy, mass spectrometry, 1H NMR, thermal analysis (TGA), magnetic measurements.
Furthermore, ligand one was analyzed by X-ray crystallography. The L1 molecule crystallised in a monoclinic crystal system with a space group P21/c, according to the X-ray single crystal analysis. The crystallisation of the compound included five water molecules. It’s interesting to note that L1 formed as a double zwitterion when the H+ of hydroxynaphthalene’s OH group moved to the nitrogen of the azomethine to produce NH+ and O moieties, with hydrogen bonding occurring between them. Additionally, the L1’s Hirshfeld surface analysis was examined.
