Powder XRD data of a microcrystalline sample of 1-Dy mounted with a minimum amount of fomblin were collected at 100(2) K using a Rigaku FR-X rotating anode single crystal X-ray diffractometer using Cu Kα radiation (λ = 1.5418 Å) with a Hypix-6000HE detector and an Oxford Cryosystems nitrogen flow gas system (Figure ). Data were collected between 2-70 °θ with a detector distance of 150 mm and a beam divergence of 1.5 mRad using CrysAlisPro. For data processing, the instrument was calibrated using silver behenate as standard, then the data were reduced and integrated using CrysAlisPro. Le Bail profile analysis was performed using JANA2006 software. Magnetic measurements of 1-Dy (Figures S72-S98 and Tables Computational methods.
