Synthesis crystal structures and magnetic properties of 2,3,6,7-Tetrakis(2-cyanoethylthio)tetrathiafulvalene polymers
Résumé
The detailed synthesis, crystal structures and magnetic properties of several transition metal complexes involving oxidized or neutral 2,3,6,7-Tetrakis(2-cyanoethylthio) tetrathiafulvalene (TCE-TTF) are presented. All compounds revealed polymeric arrangements with metal ions bridging TCE-TTF with Metal-Nitrogen bounds. Strong van-der-Waals interactions between polymers increased the dimensionality of the materials. The magnetic behaviour of hetero-bimetallic compound [M(1)$^{II}$(TCE-TTF$^{●+}$)$_2$M(2)$^{II}$(H$_2$O)$_4$](ClO$_4$)$_6$•2H$_2$O with M = Zn/Mn is also studied.
