Three Fe(III)-based coordination complexes [Fe(dqmp)2](NO3)•H2O (1), [Fe(dqmp)2](BF4)•2CH3COCH3 (2), and [Fe(dqmp)2](ClO4) (3) were synthesized from Fe(NO3)3·9H2O/Fe(ClO4)3·xH2O, NaBF4, and 2,4-dichloro-6-((quinoline-8-ylimino)methyl)phenol (Hdqmp) in methanol/acetone and characterized. The structures of complexes 1–3 were determined...
