Abstract
A novel cyano-bridged bimetallic assembly [CuL4]3[Fe(CN)6]2·2H2O (1) (L4 = 3,10-dibutyl-1,3,5,8,10,12-hexaazacyclotetradecane), which was prepared by self-assembly of [Fe(CN)6]3â 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]3â via the Fe-CNCu linkages. Magnetic studies reveal the presence of a weak antiferromagnetic interactions between the adjacent copper(II) and iron(III) ions through cyano bridges.
