(Cd2.06FeFe0.44II)-Fe-III(P2O7)2 crystallizes in the orthorhombic spac
e group C222(1) with Fe-III in a distorted octahedral environment [ave
rage Fe-O 2.05 (1) Angstrom] and Fe-II sharing sites with Cd atoms in
two sites of sixfold coordination [average Cd/Fe-O 2.20(1) Angstrom].
Two further Cd atoms show sixfold coordination with average Cd-O 2.31(
1) Angstrom.
