Abstract
- Two new heterometallic complexes, [Cu(en)(H2O)]2[Fe(CN)6]·4H2O (1) and [Cu(en)2][KFe(CN)6] (2), have been isolated from the reactions of CuCl2 and en with K3[Fe(CN)6] in different molar ratios. Both complexes have been characterized by X-ray analyses, IR spectra and elemental analyses. Complex 1 is a cyanide bridged bimetallic assembly, its crystal structure consists of a two-dimensional polymeric sheet with two different rings, one a four-membered square ring and another a 12-membered hexagonal ring. The Fe(II) ion of 1 has two terminal, two linear bridging and two 1,1 en-on bridging cyanide groups. In the crystal structure of 2, the neighboring [Fe(CN)6]3− units are bridged by the K+ and the [K[Fe(CN)6]]2− units forming a three-dimensional network structure. The [Cu(en)2]2+ units fill in the holes of the network acting as counter cations and charge compensations. Variable temperature magnetic susceptibility studies of 1 indicate that the complex exhibits ferromagnetic interaction between the Cu(II) ions. [Copyright &y& Elsevier]
