Noble‐Gas Difluoride Complexes of MOF4 (M=Mo, W); Syntheses, Structures and Bonding of NgF2 ⋅ MOF4 and XeF2 ⋅ 2MOF4 (Ng=Kr, Xe)

The NgF₂  ⋅ MOF₄ (Ng=Kr, Xe; M=Mo, W) and XeF₂  ⋅ 2MOF₄ complexes were synthesized in anhydrous HF (aHF) solvent and melts, respectively. Their single-crystal X-ray diffraction (SCXRD) structures show NgF₂  ⋅ MOF₄ and XeF₂  ⋅ 2MOF₄ have F_t -Ng-F_b - - -M arrangements, in which the NgF₂ ligands coordinate to MOF₄ through Ng-F_b - - -M bridges. The XeF₂ ligands of XeF₂  ⋅ 2MOF₄ also coordinate to F₃ OM-F_b '- - -M'OF₄ moieties through Xe-F_b - - -M …
