  Two-dimensional cyanide-bridged heterobimetallic complexes based on : Syntheses, structures and magnetic properties

  摘要：

  Using the half-sandwich tricyanometalate, KCpCo(CN)(3) (1, Cp = cyclopentadienyl), as the building block, two new cyano-bridged heterobimetallic complexes, [{CpCo(CN)(3)}(2)M(H2O)2](.)2H(2)O (M = Fe-II, 2; Co-II, 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. (c) 2006 Elsevier B.V.

  The reaction of [N(PPh(3))(2)][CpCo(CN)(3)] and [Cb*Co(NCMe)(3)]PF(6) (Cb* = C(4)Me(4)) in the presence of K(+) afforded K subset[CpCo(CN)(3)](4)[Cb*Co](4)}PF(6), [KCo(8)]PF(6). IR, NMR, ESI-MS indicate that [KCo(8)]PF(6) is a high-symmetry molecular box containing a potassium ion at its interior.

  Reaction of the salt KCpCo(CN)(3) (1) with zinc iodide leads to the formation of a highly insoluble Co(III)/Zn(II) polymeric chain. However, pyridine was found to disrupt the aggregate that is formed to yield a crystalline trimetallic complex consisting of two CpCo(CN)(3) anions bridging a Zn(py)(4) dication through the cyanide ligands, [CpCo(CN)(2)(mu-CN)](2)Zn(py)(4) (2). Along these same lines, reaction of CpCo(CN)(2)PPh3 (3) with AlCl3 or CoCl2 leads to the formation of a highly crystalline Co(II)/Co(III) diamond. [CpCo(PPh3)(mu-CN)(2)CoCl2](2) (4). Molecular Structures of 1, 2, 3 and 4 were determined by single-crystal X-ray crystallography. (C) 2003 Elsevier B.V. All rights reserved.
