摘要

The synthesis and crystal structure determination (at 293 K) of the title complex, Cs[Fe(C_8H_6BrN_3OS)_2], are reported. The compound is composed of two dianionic O,N,S-tridentate 5-bromosalicylaldehyde thiosemicarbazonate(2-) ligands coordinated to an FeIII cation, displaying a distorted octahedral geometry. The ligands are orientated in two perpendicular planes, with the O- and S-donor atoms in cis positions and the N-donor atoms in trans positions. The complex displays intermolecular N-H...O and N-H...Br hydrogen bonds, creating R44(18) rings, which link the FeIII units in the a and b directions. The FeIII cation is in the low-spin state at 293 K.
