The First Determination of Eu−H Distances by Neutron Diffraction on the Novel Hydrides EuMg2H6 and EuMgH4
Abstract
Despite the high neutron absorption of natural europium, the crystal structures of two Eu hydrides could be solved from powder diffraction data. EuMg2D6 crystallizes in a novel AB2X6 structure type (see picture), EuMgD4 is isotypic to BaZnF4. The mean Eu−D distances are 258 and 253 pm, respectively.
