Abstract: a novel tlhree dimenslonal network complex polymer,namely, GdF6 (CN)6. 4H2O; has been synthesized from water solntion of gadollinium chloride and potassium ferricyanide, The complex erystalized in the monoclinie system, space group c2; with a=12. 759 (6) b=7. 404 (1). c=13. 564 (5) A,z=4. β=90. 22 (3), Mr=441. 33,De=2. 28g/cm2, μ(Mo Kcr)=38. 36cm-1, F (000)=832, R=0. 065 for 1048 independent observed reflections. The coordinated of Fe (111) ion and Gd (111) ion are distorted octahedron and 4-capped trigonal prism, respectively. The varible- temperature magnetlc suscepttbility of the complex was measured over 4.2-300K, giving the exchange intergral 2J=-138.2cm-1,and indlcation that a mediate antiferromagnetic spinsxchange interaction between the Fe (111) ions and the Gd (111) lons within oach binuclear unit.
