Popis:	The crystal structure and magnetic properties of the hydride UCoSiH 0.7 and products of its thermal decomposition were studied. The hydrogenation of UCoSi leads to the modification of the crystal structure: the symmetry increases from orthorhombic (TiNiSi structure type) to hexagonal (ZrBeSi structure type) for UCoSiH 0.7 . UCoSi is a weak paramagnet. The hydrogenation enhances magnetic susceptibility, but does not yield magnetic ordering. The tendency observed for Curie–Weiss (CW) parameters, i.e. the shift of θ P to less negative values and slight increase of effective moments, can be understood as due to a reduction of the characteristic energy of spin fluctuations.
