Chemical compound
Manganese lactate is an organic chemical compound, a salt of
manganese and
lactic acid with the formula Mn(C3 H5 O3 )2 . The compound forms light pink crystals, soluble in water, forming crystalline hydrates.

[2]
Synthesis
Dissolution of
manganese carbonate in lactic acid solution:
MnCO3 + 2C3 H6 O3 → Mn(C3 H5 O3 )2 + CO2 + H2 O
Physical properties
Manganese lactate forms light pink crystals.
Manganese lactate is soluble in
water and
ethanol .
Manganese lactate forms crystalline hydrates of composition Mn(C3 H5 O3 )2 •n H2 O, where n = 2 and 3.
[3] Each lactate is a
bidentate
ligand . Two water molecules coordinate directly to the metal as well,
cis to each other, to complete the
octahedral cluster . In the trihydrate, the third water molecule is involved in hydrogen-bonding further away in the crystal structure.
[4]
Its dihydrate forms an
orthorhombic crystal , the space group is P 21 21 21 .
[5]
The trihydrate is a
monoclinic crystal , and the space group is P 21 .
