“…The averages of the corrected bond distances and angles are 2.058 (10) A and 108.0 (4) ° for molecule 1, and 2.062 (10) A and 107"3 (4) ° for molecule 2. They agree well with the values 2.060 A and 108-0 ° for $8(0¢) as given by Caron & Donohue (1965).…”

“…The shortest van der Waals contact is observed between S(4) and S(8"), amounting to 3.45 A. This value is comparable with 3.49 A observed in $8(c0 (Caron & Donohue, 1965) or 3.44 A for monoclinic disordered fl-sulphur, Sa(fl) (Sands, 1965). This short van der Waals contact distance is observed not only in the structure of allotropes of solid sulphur, but also in S6(NH)2, which is isostructural with S8(X).…”

The crystal structure of y-sulphur has been determined using yellow needle crystals obtained by evaporation of a pyridine solution of cuprous ethylxanthate, CuSSCOC2Hs. The crystals are monoclinic with a = 8.442 (30), b = 13.025 (10), c = 9"356 (50)/~,, fl= 124.98 (30)°; the space group is P2/c and Z= 4. The molecules of Ss(y) form a pseudo-hexagonal close-packed structure with the c axis corresponding to the unique axis of the closed-packed hexagonal structure. The molecular packing is the same as that proposed by De Haan [Physica (1958). 24, 855]. Each of the two independent molecules in the unit cell occupies a special position in such a way that the twofold rotation axis of the molecule coincides with that of the space group. The intramolecular configuration of.Ss(y) is similar to that of orthorhombic e-sulphur, $8(~). The average bond lengths and angles are: S-S = 2.044 (10) A, and S-S-S = 108.1 (4) ° for one of the two independent molecules, and S-S= 2.045 (10) A and S-S-S= 107-2 (4) ° for the other.

“…The average S-S lengths in S 6 (Donohue, Caron & Goldish, 1961), S 8 (Caron & Donohue, 1965), S~2 (Kutoglu & Hellner, 1966), S~s and Sz0 (Schmidt, Wilhelm, Debaerdemaeker, Hellner & Kutoglu, 1974) are closely similar, 2.047-2.059/~, with little scatter about the mean. Much larger variations are found in $7 (Steudel, Reinhardt & Schuster, 1977) and the oxides $70 (Steudel, Reinhardt & Sandow, 1977) and $80 (Luger, Bradaczek, Steudel & Rebsch, 1976), for instance in SvO: 1.97-2.28 A.…”
