EXAFS spectra of Hg 2ุ sorbed on goethite at pH 4.60 has revealed the existence of an inner-sphere complex with an immediate coordination shell of 2 O atoms at 2.04 ร and a further shell of 1 Fe atom at 3.28 ร . Using density functional calculations, we determined the optimized geometries of small cl
