Fig. 1. Solid state-structure of GUF-1-(HCl). (a) Infinite chain SBU of ScO₆ octahedra with bridging μ₂-OH ligands that runs down the crystallographic a-axis. (b) Fragment of the packing structure viewed down the crystallographic a-axis, with interior pore angles Ψ and Φ labelled. (c) Two-fold interpenetrated packing structure with individual nets coloured blue and yellow, and the unit cell overlaid. Where applicable, atoms are coloured Sc: purple; C: grey; O: red; H: white. H atoms and pore-bound DMF in parts (b) and (c) are omitted for clarity. Reproduced from CSD deposition 2095589.⁴⁷.
