Tailor-made trinuclear bis(oxamidato) and bis(oxamato) type complexes were synthesized.

Thin films (between 0.5 µm and 2 µm) were fabricated by spin-coating.

The film optical constants indicate the complex integrity after the deposition.

Film quality enabled first spectroscopic MOKE measurements of multi-nuclear complexes.

Magneto-optical Kerr rotation up to 11.5 mdeg was observed at RT (in 1.7 T).
