NEUTRON-DIFFRACTION STUDY ON THE INTERCALATION OF DEUTEROPYRIDINE INTO TANTALUMDISULFIDE

The intercalation of C5D5N into the lattice of 2HTaS2 was followed by neutron powder diffraction using deuteropyridine as liquid phase. Disordered second-stage nuclei were found to initiate the reaction. Model calculations established that the nuclei contain about 30% first-stage layers and that the pyridine orientations are identical in the first- and second-stage compounds. Tracer exchange measurements indicate two pyridine fractions. © 1979.
