The ground state and low‐temperature thermodynamic properties of a one‐dimensional Generalized Wigner crystal on disordered host‐lattice have been studied. It is established that the spectrum of elementary excitations has a gapless structure. An instability of the ground state with respect to arbitrary small disordering of host‐lattice is revealed. This instability leads to long‐range correlations breaking. An influence of long‐range action of the inter‐particle repulsion potential on thermodynamic properties is studied.
