(a) The crystal structure of the Ga50Pd35.5Tb14.5 2/1 PA unit cell with a lattice parameter of 23.1449 Å. Ga, Pd and Tb atoms are shown in dark blue, light blue and red, respectively. (b) Electron-density iso­surfaces derived from Fobs at the 18 e Å−3 level, highlighting the cluster core (red) and the distorted dodecahedral shell (yellow). (c) A comparison of the Tb local coordination environments in the Ga50Pd35.5Tb14.5 2/1 PA and the corresponding 1/1 PA. Adapted from Labib et al. (2023View full citation).
