摘要：
A novel cyano-bridged bimetallic assembly [CuL4](3)[Fe(CN)(6)](2)center dot 2H(2)O (1) (L-4 = 3,10-dibutyl-1,3,5,8,10,12-hexaazacyclotetradecane), which was prepared by self-assembly of [Fe(CN)(6)](3-) and [CuL4](2+), has been characterized by elemental analyses, ICP, IR. single crystal X-ray structure analysis and magnetic measurements. The structure of complex 1 consists of two distinct neutral moieties: one is a two-dimensional (2-D) polymeric layer and the other is a pentanuclear Cu3Fe2 short chain, which are supramolecular isomers and result from two different coordination modes of [Fe(CN)(6)](3-) via the Fe-C equivalent to N-Cu linkages. Magnetic studies reveal the presence of a weak antiferromagnetic interactions between the adjacent copper(II) and iron(III) ions through cyano bridges. (C) 2008 Elsevier B.V. All rights reserved.
