Web1 dag geleden · Herein, we report the first synthesis and characterization of a molecular Ra2+ compound in the solid state by single crystal X-ray diffraction, using dibenzo-30-crown-10 (DB30C10) and 226Ra. Our study reveals an 11-coordinate Ra2+ structure arising from the 10 donor atoms of DB30C10 and a bound water molecule, whereas identical …
