All data was collected using a Rigaku model XtaLAB Synergy diffractometer equipped with a Hybrid Pixel Array Detector and Cu Kα radiation (λ = 1.54184 Å). Structures were solved with the SHELXT solution program using intrinsic phasing, and refined with ShelXL 59 using least squares minimisation (Tables ), within the program Olex 2-1.5. Due to high levels of disorder, only the unit cell parameters for the family
