Polyhydrides offer intriguing perspectives as high-temperature superconductors. Here we report the high-pressure synthesis of a series lanthanum-yttrium ternary hydrides: cubic hexahydride $(La,Y)H_{6}$ with critical temperature $T_{C}$ = 237 +/- 5 K and decahydrides $(La,Y)H_{10}$ maximum ~${253 K}$ an extrapolated upper magnetic field $B_{C2(0)}$ up to ${135 T}$ at 183 GPa. This is one first ...
