Abstract: Coordination compounds of Cr(III), Ru(III), Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) ions were synthesized from the furan ligand [5-hydroxymethylfuran-2-yl-methyleneaminoquinolin-2-one] (H-MFMAQ) derived from the condensation of 5-hydroxymethylfuran-2-carbaldehyde and 1-aminoquinolin-2(1H)-one. Elemental analytical data, IR, NMR (¹H, ¹³C and ¹⁵N), EPR, XRD, SEM, TEM, EDX, TGA, mass, molar conductance, magnetic moment, and UV-Visible spectra techniques were used to confirm the structure of the synthesized chelates. According to the data obtained, the composition of the 1: 1 metal ions: furan Schiff base ligand was found to be [M(MFMAQ)Cl²] (M = Cr(III) and Ru(III)) and [M(MFMAQ)Cl(H₂O)]. nH₂O in which (M =Mn(II); n=1, Co(II); n=0, Ni(II); n = 2, Cu(II); n= 0 and Zn(II); n = 2.5). The measurements of magnetic susceptibility, ligand field parameter, and reflectance spectra suggested an octahedral geometry for the complexes. Central metals ions and furan Schiff base coordinated via O₃ and N donor sites which was observed from IR spectra. The cytotoxic activities of all inspected compounds were evaluated towards human breast (MCF-7) and lung cancer (A549) cell lines.
