Correlation between the tolerance factor and phase transition in A 4 – x B x Ni 3 O 10 ( A and B = La , Pr , and Nd ; x = 0 , 1 , 2 , and 3 )

This work shows that in the series of the Ruddlesden--Popper nickelate solid solution $A$${}_{4\ensuremath{-}x}$${B}_{x}$Ni${}_{3}$O${}_{10}$ ($A$ and $B$ = La, Pr and Nd; $x$ = 0, 1, 2 and 3) the transition temperatures as well as the room-temperature resistivities strongly correlate with the Goldschmidt tolerance factor t.
