Abstract
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.
