A cyano-bridged Mn2IIICrIII complex: Synthesis, structure and magnetic properties

A novel cyano-bridged Mn 2 III Cr III complex {Cr(CN) 4 [CNMn(salen)(MeOH)] 2 }{[Mn(salen)(CH 3 OH)(H 2 O)] 2 }[Mn(salen)(MeOH)] 2 [Cr(CN) 6 ] · 6CH 3 OH ( 1) (salen = N , N ′-ethylene-bis-salicylideneaminato) has been synthesized and structurally characterized. X-ray structure analysis reveals that in 1 , except for the trinuclear Mn 2 III Cr III unit, there exist two mononuclear Mn III and one dimeric Mn III Schiff-base units. All these structural units are linked by hydrogen bond into a 3D network. The magnetic characterization shows that compound 1 displays a weak ferromagnetic behavior.
