摘要: Abstract This contribution deals with an EXAFS investigation of Na 2 Co[Fe(CN) 6 ] at the K-edges both Fe and Co. ], a well known easily prepared mixed hexacyanoferrate, is characterised by unit cell containing linear “FeCNCo” chains where super-focusing effect may be observed K-edge transition metals. The multiple scattering (MS) signal intensity associated chain (four body contribution) comparable first shell contributions. combined fit over two edges, MS large number experimental points included in fit, permit accurate extraction structural parameters limit sensitivity.
