Investigations of structural changes happening with liquids on cooling andsupercooling continue to attract significant attention as there is still nosufficient understanding of the connection between the structural changes andthe dynamic slowdown. Previously, liquids' structures were usually discussedfrom the local perspective of individual particles. Here, we report on thestructural evolutions of the binary Kob-Andersen (KA) (4:1) and Wahnstr\"{o}m(1:1) model liquids using a different approach. The approach is based on thepreviously not discussed observation that in the liquid and supercooled liquidstates some particles form nearly linear chains in the temperature region wherethe crystallization process has not been observed. Depending on the chaindefinition, it is possible to speak about the chains containing more than 8particles. The average number of chains monotonically increases as thetemperature of the liquid decreases. Considerations of the inherent structuresshow that the number of chains remains nearly constant in the inherentstructures (IS) obtained from the parent structures (PS) above the potentialenergy landscape (PEL) crossover temperature (PELCT). Below the PELCT, theaverage number of chains in the IS increases, as the temperature of the PSdecreases. Counter-intuitively, for the KA system, below the PELCT the numberof chains in the PS can be larger than the number of chains in thecorresponding IS. The distributions of the potential energies (PE) of theparticles in chains show that the particles forming the chains tend to havehigher PE than the particles which are not in the chains. We also found thatthe particles forming the chains diffuse at a slightly lower rate than theglobal average. We also discuss the lifetimes of the chains. We compare some ofour results with the results obtained within the topological clusterclassification approach.
