Abstract

The new ionic intercalation compound (NH⁺₄)_0.22TiS^0.22-₂ has been synthesized by vacuum deintercalation of ammoniated TiS₂, characterized by thermogravimetric analysis and powder X-ray diffraction, and examined by SQUID magnetometry (indirectly), differential scanning calorimetry, incoherent inelastic neutron scattering, and nuclear magnetic resonance. Although the diffraction pattern of this compound resembles a stage-II structure in which every other van der Waals gap is occupied by NH⁺₄ it cannot be indexed completely on this basis. Magnetic and calorimetric measurements show that one electron is transferred to the host TiS₂ conduction band per NH⁺₄ cation and that the deintercalation enthalpy of NH⁺₄ is 22 kcal/mol NH⁺₄, respectively. Neutron scattering has provided evidence for an NH⁺₄ torsional fundamental mode at 215 cm^-1. The proton NMR linewidth and spin-lattice relaxation time are independent of temperature between 100 and 540 K, and the linewidth of 2.6 ± 0.3 G is in good agreement with that calculated for isotropic reorientation of the NH⁺₄ cations.
