Abstract From low-temperature Mössbauer measurement on FeC2O4·2D2O the reported difference in quadrupole splitting from the simple dihydrate is inferred to be due to lattice effects. The Zeeman split spectrum has been analyzed taking into account the ‘ambiguity problem’ and the hyperfine parameters were determined to be I.S.=1.22 mm/sec; Q.S.=1.93 mm/sec; η=0.65 to 0.72; θ=90 to 83.1o and ϕ=0 to 11.8o. The principal electric field gradient axis lies along the crystal a-axis with VYY and $$\mathop H\limits^ \to$$ lying along the crystal b-axis. The crystal field parameters 10Dq, Ds and Dt have been determined to be ∼ 10500, ∼ 185 and ∼ 211 cm−1, respectively.
