Abstract
Electron diffraction has been used to observe in situ HgxTiS2 (1.24 > x greater than or equal to 0.00) guest-layer structural behavior as a function of temperature. At low temperature (-170 degrees C), Hg forms well-ordered incommensurate one-dimensional guest chains. Heating ini tiates thermally induced chain-axis motion, interchain disorder, and d eintercalation. At higher temperatures, a novel guest-layer partial-me lting transition occurs prior to full deintercalation. The partially m elted Hg regions exhibit local hexagonal order and a weak orientationa l relationship with the host.
