| dc.description.abstractEn | CePtIn was synthesized from the elements via arc-melting and hydrogenated at 523 K and 4 MPa of hydrogen pressure leading to the hydride CePtInH0.7. The metal positions of both indides were refined from single crystal X-ray diffractometer data: ZrNiAl type, P̄62m, a = 765.3(2), c = 406.8(1) pm, wR2 = 0.0546, 276 F2 values and 14 variables for CePtIn and a = 770.6(1), c = 409.7(1) pm, wR2 = 0.0491, 354 F2 values and 14 variables for CePtInH0.7. Hydrogenation leads to an isotropic increase of the unit cell through filling of tetrahedral Ce3Pt sites. CePtInH0.7 decomposes under ambient condition within some weeks leaving the parent CePtIn structure. Magnetization measurements performed on the hydride reveal a trivalent state for the cerium but no magnetic ordering occurs above 2 K. | |
