Abstract

A simple and convenient protocol for the synthesis of the ligand 2, 5-di (2-pyridyl)-1, 3, 4- thiadiazole (dptd) has been developed. Five new 2: 1-type iron (II), cobalt (II), nickel (II) and copper (II) complexes have been prepared and structurally characterised, all of which feature the mononuclear trans-(N′, N1) 2 coordination mode. Spin crossover behaviour has been found for [FeII (dptd) 2 (NCSe) 2](2) and [FeII (dptd) 2 (NCBH3) 2]· H2O (3· H2O) ...
