The original version of this Article contained errors in the 31P NMR chemical shifts of compounds 3 and 5, due to an instrument referencing error that has been recognized later. For compound 3, an incorrect 31P NMR chemical shifts value of 150.8 ppm was reported in the 3rd sentence of the 3rd paragraph of the Synthesis subsection of the Results, in the first entry of the second line of Table 1, and in the 6th sentence of the 4th paragraph of the Discussion; an incorrect value of 150.79 ppm was reported in the 12th sentence of the section ‘Preparation of [Th(TrenTIPS)(PH)][Na(12C4)2] (3)’ of the Methods . The correct version replaces 150.8 and 150.79 with 198.8. For compound 5, an incorrect 31P NMR chemical shifts value of 24.5 ppm was reported in the 4th sentence of the 4th paragraph of the Synthesis subsection of the Results, in the first entry of the third line of Table 1, and in the 6th sentence of the 4th paragraph of the Discussion; an incorrect value of 24.46 ppm was reported in the 14th sentence of the section ‘Preparation of [{Th(TrenTIPS)}2(μ-PH)] (5).’ of the Methods. The correct version replaces 24.5 and 24.46 with 145.7. This has been corrected in both the PDF and HTML versions of the Article.
