| Abstract: | Magnesium acetate solvates, Mg(OAc)2 · nL, and their hydrates were prepared by crystallization of Mg(OAc)2 · 4H2O or Mg(OAc)2 from different solvents (L = MeOH, EtOH, HOAc). Anhydrous Mg(OAc)2 was obtained by thermal dehydration of the tetrahydrate at 150 °C. X‐ray single crystal diffraction mostly with the use of synchrotron radiation allowed the structure determination of Mg(OAc)2(H2O)3(EtOH) ( I ), Mg(OAc)2(HOAc)2(H2O)2 ( II ), Mg3(OAc)6(MeOH)6 ( III ), Mg3(OAc)6(HOAc)2(H2O)2 · 2HOAc ( IV ), Mg(OAc)2(HOAc) · 1.8(HOAc) ( V ), Mg(OAc)2 · H2O ( VI ), Mg3(OAc)6(EtOH)2] · 2EtOH ( VII ), and Mg(OAc)2 ( VIII ). Structural data were discussed in terms of the number of neutral O‐donor ligands per magnesium atom, coordination environment of magnesium atoms, structural functions of acetate groups, and hydrogen bonding systems. |
