โœฆ Synopsis

The structure of the intercalation compound K 0.7 MoS 2 as well as of its hydrated (K 0.3 (H 2 O) y MoS 2 ) and oxidation (1T-MoS 2 ) derivatives were studied by means of selected area electron di4raction (SAED). All the derivatives are shown to have superstructures related to the structure of 2H-MoS 2 . The intercalation compound K 0.7 MoS 2 has a 2a ุ‹2a-type superstructure (a โ€ซุโ€ฌ lattice parameter of 2H-MoS 2 ), whereas the superstructure of the hydrated derivative (K 0.3 (H 2 O) y MoS 2 ) corresponds roughly to an a ุ‹ a(3-type. Three domains are present in di4erent orientations, each of which can be related to each other by angles of 603 or 1203. 1T-MoS 2 has an hexagonal a(3 ุ‹ a(3-type superstructure.

This second part is devoted to the hemicarbides of the VIth transition metal group (Mo,C and W?C); a new structural transformation <-+ (E-type) is identified in Mo,C,\_, compounds, while this transition is confirmed in W,C.
