We provide experimental and theoretical evidence for the realization of the Peierls-type structurally distorted state in the quasi-one-dimensional superconductor Sc3CoC4 by a phonon-softening mechanism. The transition from the high- to the final low-temperature phase below 80 K proceeds via an extended intermediate temperature regime between 80 and 150 K characterized by phonon-driven atom displacements. In support of the low-dimensional character of the title compound we find a highly anisotropic correlation length of these dynamic distortions.
