Fe III in the high‐spin state in dimethylammonium bis[3‐ethoxysalicylaldehyde thiosemicarbazonato(2–)‐κ 3 O 2, N 1, S ]ferrate(III)


The synthesis and crystal structure (100 K) of the title compound, [(CH3)2NH2][Fe(C10H11O2N3S)2], are reported. The asymmetric unit consists of an octahedral [FeIII(L)2]− fragment, where L2− is 3‐ethoxysalicylaldehyde thiosemicarbazonate(2−), and a dimethylammonium cation. Each L2− ligand binds with the thiolate S, the imine N and the phenolate O atoms as donors, resulting in an FeIIIS2N2O2 chromophore. The ligands are orientated in two perpendicular planes, with the O and S atoms in cis positions, and mutually trans N atoms. The FeIII ion is in the high‐spin state at 100 K. The variable‐temperature magnetic susceptibility measurements (5–320 K) are consistent with the presence of a high‐spin FeIII ion with D = 0.83 (1) cm−1 and g = 2.
