Lanthanum(III) and praseodymium(III) complexes of acetylferrocenyl mercaptotriazoles

Schiff base complexes derived from 3-substituted phenyl-4-amino-thiolato-1,2,4-triazoles and acetylferrocene (LH), with lanthanum(III) and praseodymium(III) of the type M(L)₃] have been prepared and characterised by elemental analysis, electrical conductance, magnetic moments and spectral (electronic, i.r., ¹H-n.m.r. and ¹³C-n.m.r.) data. The thermal behaviour of selected complexes was investigated by t.g. and d.t.g. techniques.
