【 摘 要 】

The title neutral mononuclear complex, [1-(5-bromo-2-oxido­benzyl­idene)thio­semicarbazidato](4-bromo-2-{[2-(pyridin-2-yl)hydrazinyl­idene]meth­yl}pheno­lato)iron(III), [Fe(C8H6BrN3OS)(C12H9BrN3O)] (I), crystallizes in the monoclinic space group C2/c and has two different planar tridentate ligands. The central FeIII ion is coordinated to three N, two O and one S atom, forming a distorted octa­hedral FeN3O2S coordination geometry. In the crystal, the complex mol­ecules are linked by N—H⋯O and N—H⋯N hydrogen bonds and π–π inter­actions into layers parallel to (100). Magnetic measurements show that the central FeIII ion is in the high-spin state; this is also supported by the bond distances around the FeIII ion.
