Summary: This study demonstrates the existence of n-type thermoelectric conduction and ultra-low lattice thermal conductivity in an air-stable vacancy-ordered double perovskite Cs2SnI6. The presence of low-frequency localized optical modes and the smooth elastic lattice with chemical bonding hierarchy contribute to the low measured sound velocity and low lattice thermal conductivity. The coupling between low-energy anharmonic optical modes and heat-carrying acoustic phonons limits the phonon group velocity and lifetime, resulting in intrinsically ultra-low lattice thermal conductivity in n-type Cs2SnI6.
