Two-dimensional cyanide-bridged heterobimetallic complexes based on CpCo ( CN ) 3 - : Syntheses, structures and magnetic properties Academic Article uri icon


  • Using the half-sandwich tricyanometalate, KCpCo(CN)3 (1, Cp = cyclopentadienyl), as the building block, two new cyano-bridged heterobimetallic complexes, [{CpCo(CN)3}2M(H2O)2] · 2H2O (M = FeII, 2; CoII, 3), have been synthesized and structurally characterized. Complexes 2 and 3 are isostructural. In each complex, [CpCo(CN)3]- acts as a bis-monodentate bridging ligand toward the central [M(H2O)2]2+ core through two of its three cyanide groups, which leads to a two-dimensional network layer structure with a repeating cyclic octameric [(-M-NC-Co-CN-)]4 unit. The magnetic properties of complexes 2 and 3 have been investigated in the temperature range of 2.0-300 K and they both show weak antiferromagnetic interaction. © 2006 Elsevier B.V.
