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, ∞).展开更多
