Synthesis, crystal structure and magnetic properties of a new mixed-valence [Mn4IIIMnII] pentanuclear complex†
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.
