| Abstract |
The one-pot reaction of copper powder, sodium nitroprusside, ammonium thiocyanate and 2,2 -bipyridine (bpy) in acetonitrile solution at ambient conditions of air and water yields the novel heterometallic [Fe2Cu2(bpy)(6)(mu-CN)(4)(NCS)(2)](2)[Fe(CN)(5)(NO)](NCS)(2)center dot 5H(2)O complex 1, which has been structurally and magnetically characterized. The most prominent feature of this complex is the unique tetranuclear (Fe2Cu2II)-Cu-II squares comprised [Cu(bpy)NCS](+) and [Fe(bpy)2](2+) corners with CN edges. The Cu...Cu and Fe...Fe separations are similar to 6.72 and similar to 7.73 A, respectively. The variable-temperature magnetic susceptibility study revealed that a very weak antiferromagnetic coupling is active between Cu(II) centers (J(CuCu) = -0.37 cm(-1)).
