Short summary
The crystal structure of the mineral decrespignyite-(Y) from the Paratoo copper mine (South Australia) has been obtained by applying δ recycling direct methods to 3D electron diffraction data followed by Rietveld refinements of synchrotron powder diffraction data. Its structure mainly shows a metal layer sequence of polyhedra interconnecting hexanuclear (octahedral) oxo-hydroxo yttrium clusters along a ternary axis or tilted clusters to hetero-tetranuclear ones hosting Cu, Y and rare earths.
