This contribution reports the synthesis and characterization of the organothorium alkylthiolate complex [(CH3)5C5]2Th(SCH2CH2CH3)2. This compound crystallizes in the monoclinic space group C2/c (#15) with four molecules in a cell of dimensions a=19.066(2), b=11.603(1), c=16.379(2) Å, and β=130.08(1)°. Least-squares refinement led to a value for the conventional R index (on Fo) of 0.040 for 132 variables and 2030 observations having Fo 2≥3σ(Fo 2). The molecular structure consists of an unexceptional 'bent sandwich' [(CH3)5C5]2Th fragment coordinated to two n-propylthiolate ligands. The ThS bond distance is 2.718(3) Å; the SC(α) distance, 1.78(2) Å; the ThSC(α) angle, 108.3(5)°; and the SThS′ angle, 102.5(2)°. Contrasts are drawn with the structures of analogous actinide alkoxides.
