✦ Synopsis

The intercalation and deintercalation of NH 3 into ZrS 2 has been investigated by evolved gas analysis, thermogravimetric analysis, di4erential scanning calorimetry, vapor pressure measurements, SQID magnetometry, and X-ray powder di4raction. Ammonia intercalation of ZrS 2 , in contrast to other transition metal disul5des (TS 2 ), is predominately a molecular insertion reaction. Only a small amount of NH Ψ‰ 4 (41%) is present in the intercalate, which may be required for intercalation to occur. The small degree of charge transfer can be understood qualitatively within the rigid-band model. The equilibrium intercalate, (NH 3 ) 0.92 ZrS 2 , can be indexed to a 3R, stage-1 structure having an occupied layer expansion (3.17 A s ) in good agreement with other NH 3 +TS 2 intercalation compounds. The guest+guest and guest+host interactions that stabilize the intercalate apparently involve H 2 N+H2NH 3 and H 2 N+H2S hydrogen bonding, respectively. Based on this study, ammoniated ZrS 2 o4ers an excellent model system for probing the structure and properties of molecular guest species in lamellar materials.

The reactions of methylamine, dimethylamine, and trimethylamine with TiS 2 were characterized by several techniques. Detailed studies of the intercalation of methylamine demonstrated that the reaction was of the redox-rearrangement type, where the intercalate is best described as (CH 3 NH Ψ‰ 3 ) y (C
