composition was confirmed by energy‐dispersive X‐ray spectra (Sn0.98(5)Pd3.02(5)). X‐ray diffraction showed an ordered AuCu3 type structure [Pm3m, a = 397.799(1) pm]. SnPd3 takes up hydrogen at 703 K under 5.0 MPa, resulting in a volume expansion of 0.4 %. The crystal structure was determined from neutron powder diffraction data of the deuteride. SnPd3D0.138(7) belongs to the cubic anti‐perovskite type [Pm3m
