title: 4-[(E)-2-Ferrocenylethen-yl]-1,8-naphthalic anhydride.
abstract: In the structure of the title compound, [Fe(C(5)H(5))(C(19)H(11)O(3))], the plane of the substituted ferrocene ring is tilted by 14.17 (6)° with respect to the mean plane through the naphthalene ring system. In the crystal structure, centrosymmetric dimers are formed through π-π inter-actions [centroid-centroid distance = 3.624 (2) Å] between the substituted ferrocene ring and the three fused rings of the naphthalic anhydride unit. Pairs of dimers are held together by further naphthalene-naphthalene π-π interactions [distance between parallel mean planes 3.45 (3) Å]. Each dimer inter-acts with four neighbouring dimers in a herringbone fashion through C-H⋯π inter-actions, so forming a two-dimensional sheet-like structure.
