Abstract

A new iron molybdophosphate, (NH₃CH₂CH ₂NH₃)₈(H₃O)_1.3Fe _0.3^IIFe_0.7^IIMo₁₂O ₃₂-(HPO₄)₂(H₂PO₄) ₆(OH)6·8.7H₂O (1) has been synthesized under hydrothermal conditions and structurally characterized by single crystal X-ray diffractions. It crystallizes in the monoclinic, space group P2(1)/n, a = 15.845(7) Å, b = 15.867(7) Å, c = 17.132(8) Å, β = 92.794(5)°, Z = 2. The crystal structure of 1 contains the isolated polyanion units [FeMo₁₂O₃₂(HPO₄) ₂(H₂PO₄)₆(OH)₆] around which the portonated ethylenediamine ions, lattice water and the protonated water molecules are positioned. By hydrogen bond interactions the polyanions are interconnected to form a novel three-dimensional iron molybdophosphate. The Mössbauer spectra quantitatively ascertain the assignment and distribution of iron oxidation states, and reveal the properties of the magnetic structure. Other characterization by IR and thermal analysis are also described.
