Abstract: Herein, we report the synthesis and molecular structures of various magnesium(ii)-phosphate monoesters. By using a bulky aryl substituted phosphate monoester, ArOPO <subscript>3</subscript> H <subscript>2</subscript> (Ar = 2,6-(CHPh <subscript>2</subscript> ) <subscript>2</subscript> -4-tBu-C <subscript>6</subscript> H <subscript>2</subscript> ), we have reproducibly assembled mono-, di-, tetra- (cage and ring), hexa-, and polynuclear magnesium(ii)-phosphate monoesters. Interestingly, the hexanuclear magnesium(ii)-phosphate monoester encapsulates an open-cage dodecanuclear water cluster.
