A novel octamolybdate complex, [Fe(2,2-bipy)3]2[Mo8O26]·6H2Ohas been synthesized via the hydrothermal technique, and it crystallizes in monoclinic, space group P21/c with two molecules in a unit cell: a = 1.2 1 512(5), b = 1.36840(5), c = 2.18823(9) nm, β = 90.515( 1 )°, Mr = 2340.42, Z = 2, V = 3.6384(2) nm3, Dc = 2.136 g/cm3, F(000) = 2296, λ,(MoKα) = 0.071073 nm, μ = 1.813 mm 1, R =0.0719 and wR = 0.1093 for 4058 observed reflections with I≥2σ(I). The structure is characterized by the co-existence of octahedral [Fe(2,2′-bipy)3]2+ cations and β-octamolybdate [Mo8O26]4- anions. The magnetic susceptibility data show a Curie-Weiss paramagnetic behavior (θ = -5.201 K) in accordance with the spin-only ground state of Fe11 ions. IR, UV-Vis, and EPR spectra are also briefly noted in this paper.
