Abstract:	Novel dinuclear iron (III) complex Fe₂(HPTB) 1μ-O₂P(OPh)₂ O₂P(OPh)_{2 2}] (C1O₄)₂, where HPTB is the anion of N, N, N′, N′-tetrakis(2-benzimidawlylmethyl)-2-hydroxy-1, 3-diaminopropane, was prepared in order to provide a model for the active site of purple acid phosphatase (PAP). This compound has been characterized by X-ray crystallography. Crystal data: triclinic, space group $P \bar 1$ ,a = 1. 512 13(5), b = 1. 591 19(5),c = 1.890 90(5) nm, α = 69.925(1)°,β = 84. 358(1)°,γ = 65.712(1)°, Z = 2. Dinuclear iron (II1) centers are bridged by aμ-OR group from HPTB, a bidentate bridging diphenylphosphate and two terminal diphenylphosphates coordinate to Fe(III) centers.

Keywords:	dinuclear iron(III) complex model compound purple acid phosphatase
