To establish p-d interactions in molecule-based multifunctional materials, the dimeric [Ni₂Cl₂(L)₂](I₅)₂(I₃)₂I₂ has been synthesized.
It reveals ferromagnetic exchange interactions between the four different spin carriers (L = 4,5-bis(2-pyridylmethylsulfanyl)-4´,5´-ethylenedithiotetrathia fulvalene).

This work was carried out by Shi-Xia Liu in the group of Prof. Silvio Decurtins.
