Synthesis, structure and magnetic characterization of a one-dimensional iron phosphate, [NH3CH2CH2CH(NH3)CH2 CH3](2+1)(proportional to)[FeF(HPO4)(2)](2-)

摘要

The hydrothermal synthesis, structure and magnetic studies of a one-dimensional iron fluro-phosphate, [NH3CH2CH2CH(NH3)CH2CH3](proportional to)(2+1)[FeF(HPO4)(2)](2-), I, is presented. The structure, solved by single-crystal X-ray diffraction, consists of isolated (1)(proportional to)[FeF(HPO4)(2)](2-) chains of the tancoite type with diprotonated amine molecules situated in between. Magnetic studies indicate anti-ferromagnetic interactions. Crystal data: space group = P2(1)/m (no. 12), a = 8.846(2) Angstrom, b = 7.211(1) Angstrom, c = 9.893(2) Angstrom, beta = 97.10(3)degrees, V = 626.2(2) Angstrom(3), Z = 4, rho(cale) = 1.968 g cm(-3), mu(MoKalpha) = 1.511 mm(-1), R-1 = 0.044, wR(2) = 0.099, S = 1.016 for 134 parameters.
