Interacciones magnéticas en clusters de valencia mixta y clusters encapsulados por polioxotungstatos : síntesis de materiales formados por polioxoaniones y radicales orgánicos

A new Co(II) coordination solid with mixed oxygen, carboxylate, pyridine and thiolate donors exhibiting canted antiferromagnetism with TC ≈ K

Reaction of Co(II) chloride with the sodium salt of 2-mercaptonicotinic acid in water at 200 ºC results in the formation of Co4(2-mna)4(H2O), which orders as a canted antiferromagnet at 68 K. Gomez Garcia, Carlos Jose, Carlos.Gomez@uv.es
