Abstract: In the title complex, [Mn(C₁₂H₁₆NO₅)₂]·2CH₃OH·0.5H₂O, the Mn^II atom has a distorted octahedral coordination geometry in which two N atoms from two 6-methoxy-2-[tris(hydroxymethyl)methyliminomethyl]phenolate ligands adopt a trans arrangement. The Mn-O(H) bonds (mean length 2.134 Å) are significantly longer than the Mn-O and Mn-N bonds (mean length 2.011 and 2.027 Å, respectively), and the dihedral angle between the mean planes through the aromatic rings of the two ligands is 76.8 (1)°. A complex network of O-HO hydrogen bonds is formed between the complexes and the uncoordinated methanol and water molecules. The C and O atoms of one C-OH group are disordered with equal occupancies.
