摘要

One-pot reaction of copper(II) chloride dihydrate CuCl2 (.) 2H(2)O with sodium adipate Na(2)adip (adip(2-) = O2C(CH2)(4)CO22-) in the presence of 2,2'-bipyridyl (bpy = C10H8N2) and potassium 1,1,3,3-tetracyano-2-ethoxypropenide (tcnp- = (NC)(2)CC(OEt)C(CN)(2)(-)) gives the new compound [Cu-4(bpy)(4)(adip)(3)](tcnp)(2) (1), which was characterized by single crystal X-ray diffraction analysis. Each metal ion presents an elongated square pyramidal CuN2O3 environment, with an oxygen atom in apical position and a base plane involving almost equivalent bond lengths. The structure can be described as a pseudo dinuclear species in which two Cu(bpy) units are triply bridged by two unsymmetrical bridging oxygen atoms of two carboxylate groups with a k-mu-bridging mode and by an almost symmetrical OCO unit with a bidentate syn-syn k:k-mu-bridging mode. Such coordination modes generate the tetranuclear Cu-2(adip)(2)Cu-2 units which are bound by a symmetrical adipate ligand through a k-mu-bridging mode to lead to infinite chains involving a succession of Cu, units alternatively bridged by one or two aliphatic chains of adipate ligands. Magnetic measurements exhibit a maximum in the chi(m) versus T plot (at similar to 15.2 K), which is characteristic of weak antiferromagnetic exchange interactions between the Cu(II) ions bridged by the carboxylate groups. Fit of the magnetic data with appropriate model led to J value of -7.74 cm(-1) (the Hamiltonian is written as H = -2JS(a)S(b)). (c) 2006 Elsevier B.V. All rights reserved.
