X-ray single crystal analysis shows that compound 1 exhibits a nonlinear [Ru3] 7 + backbone (∠ = 170.26(3)) with long Ru-Ru bond lengths (2.3554(8) Å). The long Ru-Ru distances observed for 1 decrease the Ru-Ru interactions and electric conductance. Magnetic measurements indicate that compound 1 is in a S = 1/2 state. DFT calculations suggest that this unpaired electron occupies the π* orbital which is stabilized by π-acid NCS- ligands and thus weakening the Ru-Ru π interaction. © 2013 Published by Elsevier B.V.
