A new mononuclear neutral high-spin iron(III) complex with the different tridentate ligands 5-bromo-salicyl-aldehyde (pyridin-2-yl)hydrazone and 5-bromo-salicyl-aldehyde thio-semicarbazone.

ABSTRACT: The title neutral mononuclear complex, [1-(5-bromo-2-oxido-benzyl-idene)thio-semicarbazidato](4-bromo-2-{[2-(pyridin-2-yl)hydrazinyl-idene]meth-yl}pheno-lato)iron(III), [Fe(C₈H₆BrN₃OS)(C₁₂H₉BrN₃O)] (I), crystallizes in the monoclinic space group C₂/c and has two different planar tridentate ligands. The central Fe^III ion is coordinated to three N, two O and one S atom, forming a distorted octa-hedral FeN₃O₂S coordination geometry. In the crystal, the complex mol-ecules are linked by N-H⋯O and N-H⋯N hydrogen bonds and π-π inter-actions into layers parallel to (100). Magnetic measurements show that the central Fe^III ion is in the high-spin state; this is also
