The structure of the title complex, [Fe(C5H5)(C10H13O3)], shows the occurre
nce of two stereogenic centres in the hydroxymethyl-1,3-dioxane fragment. T
he S configuration found for these chiral C atoms agrees with the synthetic
route. The dioxane ring has a nearly perfect chair conformation. O-H ... O
hydrogen bonds result in the formation of an eight-membered ring built fro
m the arrangement of four complex molecules around a fourfold axis.
