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

Abstract

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)°. The Fe atom is slightly closer to the substituted cyclopentadienyl ring, with an Fe–centroid distance of 1.6510 (8) Å, compared with 1.6597 (8) Å for the unsubstituted ring. The bridging unit between the substituted Cp ring and the naphthyl ring system is planar within 0.0174 Å and makes dihedral angles of 59.032 (10) and 66.02 (2)°, respectively, with these two rings. The angle between the substituted Cp ring and the naphthyl ring system is 72.094 (18)°. 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...S hydrogen bonds.
