Molecules of ferrocene-1,1′-diylbis(2-phenylethanedione), [Fe(C₁₃H₉O₂)₂], lie across twofold rotation axes. One of the O atoms in each diketone unit acts as an acceptor of two intermolecular C - H···O hydrogen bonds. Hydrogen bonds employing cyclopentadienyl C - H bonds as donors generate spirals of molecules around the 3₁ axes, while those employing phenyl C - H bonds as donors generate two-dimensional sheets.
