“…Based on the INADEQUATE results the P (3) species are mostly connected among themselves, forming electrically neutral molecular and/or segregated polymeric structures. This kind of molecular-level segregation which is also characteristic of binary phosphorus-sulfur glasses [32] portrays a rather inhomogeneous nanostructure of these materials. In spite of these findings, the differential scanning calorimetry plots give no indication of macroscopic phase separation.…”

“…3 confirm the presence of multiple P peaks from trigonal PS 3/2 and tetrahedral S = PS 3/2 units. Both of these, due to the asymmetry of their S atom arrangements, would give rise to asymmetric lineshapes in the static 31 P NMR spectra of P-rich glasses [9]. On the other hand, the PS 4/2 unit would appear in the wideline 31 P NMR spectra as a highly symmetric resonance.…”

“…There have been many structural studies of P-containing sulfide glasses, including a number of 31 P NMR studies of P speciation. Eckert and coworkers examined the binary P-S system, demonstrating changes in P coordination necessary to accommodate the glass stoichiometry [8][9][10]. Cherry et al have utilized a number of experimental approaches to characterize the glass structure in the GeP sulfide system [11].…”

“…An attempt has been made to correlate the "P chemical shift anisotropy with the distortion from local C,, symmetry (33). However, using additional data from a more recent study (34), the previous simple correlation was found to be invalid (35). With P1 bonded to two sulphur atoms and one phosphorus atom, its chemical shift anisotropy, AS = 154 ppm, is smaller than the value, AS = 257 ppm, found for the apical 3 1~ in P4S3, 2; the two P-S bonds in 1 are much longer than the P-S bonds in P,S,.…”

GANG WU, RODERICK E. WASYLISHEN, WILLIAM P. POWER, and GRAZLANO BACCOLINI. Can. J. Chem. 70, 1229Chem. 70, (1992. Phosphorus-31 NMR static powder spectra and high-resolution magic angle spinnlng spectra have been obtained for a new heterocyclic compound, cis-2,10-dimethyl[l,2,3]benzothiad~phospholo[2,3b][1,2,3]benzothiadiphosphole (I), which contains a P(II1)-P(II1) single bond. The homonuclear 3 1~-3 '~ dipolar interaction manifests itself in both the magic angle spinning spectra and the non-spinning llne shape. Under the AX spin pair approximation, analysis of the spinning sidebands in the MAS experiment yields a full characterization of the two 3 1~ chemical shielding tensors. This approxlmation is confirmed by the exact powder line shape simulation for a homonuclear spin pair. Analysis of the dipolar subspectra also yields the absolute sign of 'J(P,P), which is found to be negative. (I), qui contient une liaison simple P(II1)-P(II1).
