³¹P Nuclear Magnetic Resonance Spectroscopy as a Probe of Thorium-Phosphorus Bond Covalency: Correlating Phosphorus Chemical Shift to Metal-Phosphorus Bond Order.

ABSTRACT: We report the use of solution and solid-state ³¹P Nuclear Magnetic Resonance (NMR) spectroscopy combined with Density Functional Theory calculations to benchmark the covalency of actinide-phosphorus bonds, thus introducing ³¹P NMR spectroscopy to the investigation of molecular f-element chemical bond covalency. The ³¹P NMR data for [Th(PH₂)(Tren^TIPS)] (1, Tren^TIPS = {N(CH₂CH₂NSiPrⁱ₃)₃}^3-), [Th(PH)(Tren^TIPS)][Na(12C4)₂] (2, 12C4 = 12-crown-4 ether), [{Th(Tren^TIPS)}₂(μ-PH)] (3), and [{Th(Tren^TIPS)}₂(μ-P)][Na(12C4)₂] (4) demonstrate a chemical shift anisotropy
