We report the pressure dependence up to 95 kbar of Raman-active stretching modes in the quasi-one-dimensional [ital MX] chain solid Pt[sub 2]Br[sub 6](NH[sub 3])[sub 4]. The data indicate that a predicted pressure-induced insulator-to-metal transition does not occur, but are consistent with the solid undergoing either a three-dimensional structural distortion or a transition from a charge-density wave to another broken-symmetry ground state. We show that such a transition can be well modeled within a Peierls-Hubbard Hamiltonian.
