Fig. 2. Characterization data for 1. (A) Partial 31P{1H} NMR spectrum of 1 in toluene-d8. (B) A plot of 31P{1H} NMR chemical shift versus T−1 for the 30 ppm (25 °C) resonance. (C) Variable temperature magnetic susceptibility (χT) for 1 collected at 10 000 Oe. (D) Partial ESI-MS mass spectrum of 1 in THF (capillary voltage of 2.50 kV, positive ion mode) showing a peak at 3572.43 m/z assignable to [Ni30S16(PEt3)11]+ (calcd 3572.57 m/z).
