Tetrathiafulvalene [FeIII(C2O4)Cl2]: An Organic–Inorganic Hybrid Exhibiting Canted Antiferromagnetism

A new organic–inorganic hybrid, (TTF+)FeIII(C2O4)Cl2, displaying canted antiferromagnetism has been prepared and characterized, where the tetrathiafulvalene (TTF) molecules are face-to-face dimers and the anion is a one-dimensional coordination polymer (see Figure). Due to π–d interactions through short S…Cl and S…O contacts a three-dimensional Néel state is stabilized at the high temperature of 20 K.
