Solving the ³¹P{¹H} NMR spectrum of (Me₃Si)₃P₇ as B[AC]₃ case

GRAPHICAL ABSTRACT

ABSTRACT

³¹P NMR chemical shifts and coupling constants of (Me₃Si)₃P₇ in solution state reveal C₃ symmetry which is consistent with a twisted molecular framework as found in solid state. The ³¹P{¹H} NMR spectrum was iterated as a B[AC]₃ system by automated line shape analysis using DAISY under TOPSPIN.
