Abstract Effect of structure parameter n and its coupling with the connection mode among RuO6 octahedra of Srn+1RunO3n+1 (n=1, 2, ∞) are investigated. The gradually enhanced rotation and tilting effect with increasing n are observed in Srn+1RunO3n+1. Besides, the chemical valence of Ru is not changed, while the one of Sr gradually varies with increasing n, which highlights the great contribution of connection mode to the chemical environment. Our results show a strong n dependence on the connection mode between octahedra in Srn+1RunO3n+1 (n=1, 2, ∞).

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
