Synthesis crystal structures and magnetic properties of 2,3,6,7-Tetrakis(2-cyanoethylthio)tetrathiafulvalene polymers.

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^●+)₂M(2)^II(H₂O)₄](ClO₄)₆•2H₂O with M = Zn/Mn is also studied. [ABSTRACT FROM AUTHOR]
