1-[(Ferrocen-1-yl)methyl]-3-(naphthalen-1-yl)thiourea

In the title compound, [Fe(C5H5)(C17H15N2S)], the cyclopentadienyl (Cp) rings are almost parallel and essentially eclipsed, with a dihedral angle between the Cp ring planes of 0.807 (11)degrees. The Fe atom is slightly closer to the substituted cyclopentadienyl ring, with an Fe-centroid distance of 1.6510 (8) angstrom, compared with 1.6597 (8) angstrom for the unsubstituted ring. The bridging unit between the substituted Cp ring and the naphthyl ring system is planar within 0.0174 angstrom and makes dihedral angles of 59.032 (10) and 66.02 (2)degrees, respectively, with these two rings. The angle between the substituted Cp ring and the naphthyl ring system is 72.094 (18)degrees. The H atoms of the NH groups of the thiourea moiety are positioned anti with respect to each other. In the crystal, molecules form centrosymmetric dimers via pairs of N-H center dot center dot center dot S hydrogen bonds.
