Abstract

A novel pentanuclear mixed-valence manganese (II/III) complex [Mn₅Na₂O₂(O₂CMe)₄(L′)₄(DMF)₄(H₂O)]·3DMF (where H₂L′ = 2-hydroxyphenyl-1,3,4-oxadiazole-2(3H)-thione) has been synthesized, structurally and magnetically characterized and presents a butterfly-type spin topology with competing antiferromagnetic interactions.
