In the crystals of 5-hexafluoropentane-2,4-dionato-O,O')manganese(ll)
monohydrate, [Mn(C5HF6O2)(2)(H2O)(2)].H2O, the Mn atom and all three w
ater molecules lie on a crystallographic mirror plane. Two of the wate
r molecules are coordinated to the Mn atom in a trans geometry and the
third links the structure into hydrogen-bonded sheets. The two planar
hexafluoroacetylacetonato ligands related by the mirror plane form a
dihedral angle of 41.6(2)degrees with one another. One CF3 group displ
ayed significant disorder.
