Crystal Structure of Bis(μ-hydroxo)diiron(III) Complex with Tripodal Ligands Having a Terminal Carboxylate Group

The structure of the dinuclear Fe(III) complex [Fe2(6Me2-BPP)2(OH)2](NO3)1.9553·Br0.0447·8H2O (1) was determined by X-ray crystallography, where 6Me2-BPP is N,N-bis(6-methyl-2-pyridylmethyl)-3-aminopropionate. The compound crystallizes in a triclinic space group, P1, with a = 10.3845(15), b = 11.1976(15), c = 20.389(4)Å, α = 82.119(10), β = 85.340(10), γ = 68.871(7)°, Z = 2, V = 2189.3(6)Å3. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0342 and 0.0972, respectively, for all 9586 independent reflections. The complex has a bis(μ-hydroxo)diiron core structure.
