Cover illustration: The molecular structure of trans-bis(3-benzyl-1-ferrocenylmethyl-1H-imidazolidin-2-ylidene)diiodidopalladium(II), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 30% probability level. H atoms have been omitted for clarity. See Daran, Demirhan, Yildirim & Çetinkaya [Acta Cryst. (2012), C68, m48-m52].
The nominal composition LiFeW2O8 and space-group symmetry were confirmed by single-crystal X-ray diffraction. More accurate atomic coordinates and atomic displacement parameters have been established. The refinement led to better residuals (R = 0.0177) than reported in a previous determination of this structure.
