Abstract:	The title compound absorbs slowly hydrogen at 523 K under a pressure of P(H₂)=1 MPa, giving the new hydride Ce(Ni_0.82Cu_0.18)SnH_1.7(1). The hydrogenation induces both: (i) a structural transition from orthorhombic TiNiSi-type to hexagonal ZrBeSi-type and (ii) a magnetic transition from antiferromagnetic to ferromagnetic ordering This behaviour is compared to that observed recently during the hydrogen insertion into the Kondo semi-metal stannide CeNiSn.
