Phosphorus-31 nuclear magnetic resonance studies of solid diphosphine disulphides. Crystallographic considerations

Abstract

High-resolution ³¹P n.m.r. spectra have been obtained for a number of solid diphosphine disulphides under conditions of high-power decoupling, cross-polarization and magic-angle rotation. The results yield crystallographic information about the size of the asymmetric unit and are consistent with data from X-ray diffraction work when known. In one case, evidence of morphological variation is obtained.
