X-ray diffraction study of α-34S within temperature range 100–363 K

Аннотация

α-³⁴S has been studied with X-ray crystallography within 100–363 K. Anisotropy of the evolution of the parameters of the orthorhombic unit cell has been examined. The absolute increase in the cell volume is 154 ų, and the relative one is 4.8%. It has been demonstrated that in the studied range the intramolecular S–S bond lengths are shortened at average by 0.006 Å on heating. At the same time, intermolecular contacts S…S shorter than the sum of van der Waals radii demonstrate average elongation of 0.097 Å.
