“…Crystalline c-P 2 S 5 comprises cagelike P 4 S 10 molecular units in which each phosphorus atom is tetrahedrally bonded to four sulphur atoms with one P-S double bond of length 1.91 -1.98 Å and three P-S single bonds of length 2.02 -2.13 Å. [38][39][40] In the P 4 S 10 molecule, coordination numbers of n P P ϭ3 and n S S ϭ4.6 are obtained for the ranges 3.37рr(Å)р3.44 and 3.24рr(Å)р3.46, respectively. However, integration of the second peak in ⌬G (1) (r) ͑Fig.…”

The structure of the glassy fast-ion conductor g-AgPS 3 is studied by using the method of isotopic substitution in neutron diffraction. The diffraction pattern measured in a single experiment is separated into its contributions from the partial structure factor S AgAg (k), and related difference functions ⌬ Ag (k) and ⌬ (k) comprising the Ag-and -correlations, respectively, where denotes a matrix atom ͑P or S͒ and k the scattering vector. It is found that the glass structure is significantly different from that of the corresponding crystalline compound c-AgPS 3 . The P 2 S 6 2Ϫ units of the crystal are broken up to form tetrahedral PS 4 motifs with a P-S bond distance of 2.04͑2͒ Å which are linked to form a matrix having pronounced intermediate-range order. The data for g-AgPS 3 are consistent with a model wherein the silver ions, coordinated to an average of 2.5͑2͒ S at a bond distance of 2.53͑2͒ Å, move via pathways which have a large distribution of Ag-Ag sites: in real space the Ag-Ag correlations are characterized by a broad ''liquidlike'' distribution with a nearestneighbor distance of 2.9͑1͒ Å and coordination number of 1.1͑2͒. ͓S0163-1829͑98͒07334-2͔

“…The structures of α-P 4 S 3 , [1] γ-P 4 S 3 , [1,2] α-P 4 S 4 , [3] α-P 4 S 5 , [4] β-P 4 S 5 , [5] β-P 4 S 6 , [6] α-P 4 S 7 , [4,7] β-P 4 S 7 , [8] P 4 S 9 -II, [9] P 4 S 9 -III, [10] and P 4 S 10 [4,7,11] were determined from single-crystal X-ray diffraction. Other phosphorus sulfides like P 4 S 8 have been characterized by 31 P NMR spectroscopy.…”
