The two insertion reactions of [(CH3C5H4)2Nd(μ-SPh)(THF)]2 (1) with PhNCO and PhNCS in a 1:1 mole ratio in tetrahydrofuran (THF) solution were studied. The first reaction gives the dimeric complex [(CH3C5H4)2Nd]2[μ-η2-OC(SPh)NPh]2 (2), which has an interlinked tricyclic structure formed via two bridged Nd−O bonds, while the second reaction affords the complex (CH3C5H4)2Nd[η2-SC(SPh)NPh](THF) (3), containing a η2-coordinated ligand of SC(SPh)NPh. The new complexes, including 1, were fully characterized by IR, elemental analysis, and single-crystal X-ray diffraction.
