  We investigated the equilibrium properties of a one-dimensional system of
classical particles which interact in pairs through a bounded repulsive
potential with a Gaussian shape. Notwithstanding the absence of a proper
fluid-solid phase transition, we found that the system exhibits a complex
behaviour, with "anomalies" in the density and in the thermodynamic response
functions which closely recall those observed in bulk and confined liquid
water. We also discuss the emergence in the cold fluid under compression of an
unusual structural regime, characterized by density correlations reminiscent of
the ordered arrangements found in clustered crystals.
