A d-f heterodinuclear complexes [Fe(phen)(3)](2)[FeCe(tiron)(3)]center dot 6H(2)O (tiron=C6H2O8S2) was isolated from the hydrothermal reaction of Ce(NO3)(3)center dot 6H(2)O, Fe(NO3)(3)center dot 9H(2)O, 1,10-phenanthroline and 4,5-dihydroxybenzene-1,3-disulfonate, and characterized by elemental analysis, IR, UV, TG and single-crystal X-ray diffraction analysis. The complex crystallized in the cubic system, space group P2(1)3 with the cell parameters: a=2.194 09(4) nm, V=10.562 4(3) nm(3), Z=4, F(000)=4 648, R-1=0.045 1, wR(2)=0.107 7, S=1.07. In [FeCe(tiron)(3)](6-) unit with symmetry of C-3 was revealed that the Fe3+ ion is in a FeO6 distorted trigonal anti-prism coordination polyhedron completed by six phenolate O atoms from three tiron(-) ligands, and Ce3+ in a CeO6 distorted trigonal anti-prism coordination polyhedron completed by three phenolate mu(2)-O atoms and three O atoms from sulfonic group of three ligands. The [Fe (phen)(3)](3+) cations and [FeCe(tiron)(3)](6-) anions via pi-pi interaction between phen ligands and electric attraction between cations and anions was assembled into pseudo Host-guest type supramolecule in bougainvillea glabra-like. The magnetic properties of the complex has been determined in the temperature range 2-300 K, indicating that the antiferromagnetic interaction between the central Ce(III)-Fe(III) ions. CCDC: 728509.
