Abstract
A recent analysis of Mossbauer hyperfine interaction data for the octahedral 3d (t2g5) Fe III complex in K3Co1-xFex(CN)6 led to values of the contact field constant differing in sign and order of magnitude from free-ion estimates (see abstr. A68613 of 1972). This was interpreted in terms of a covalent expansion of the 3d electron wavefunctions to a degree previously unsuspected. It is shown that the analysis was based on several theoretical misconceptions and as a result is incorrect.Keywords
