摘要：
A novel cyano-bridged (Mn2CrIII)-Cr-III complex {Cr(CN)(4)[CNMn(salen)(MeOH)](2)}{[Mn(salen)(CH3OH)(H2O)](2)}[Mn(salen)(MeOH)](2)-[Cr(CN)(6)] center dot 6CH(3)OH (1) (salen = N,N'-ethylene-bis-salicylideneatninato) has been synthesized and structurally characterized. X-ray structure analysis reveals that in 1, except for the trinuclear (Mn2CrIII)-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. (C) 2008 Elsevier B.V.
