Abstract 2‐(((2‐Hydroxy‐3‐methoxyphenyl)methylene)amino)‐2(hydroxymethyl)‐1,3‐propanediol (LH 4 , as abbreviation) reacts with MnCl 2 · 4H 2 O, CoCl 2 · 6H 2 O, and Cu(ClO 4 ) 2 · 6H 2 O to give the new complexes [Mn(LH 2 ) 2 ] ( 1 ), [Co 2 Cl(H 2 O)(LH 2 ) 2 ] · 4H 2 O ( 2 ), and [Cu 4 (LH 2 ) 4 (H 2 O) 4 ] ( 3 ). Complex 1 is formed by the assembly of two molecules of the ligand with one manganese(IV) ion. In the mixed‐valence cobalt complex 2 there is an asymmetry between the coordination spheres of cobalt(II) and cobalt(III). In the tetramer 3 four copper(II) ions attain a distorted tetrahedral configuration surrounded by four molecules of the ligand.
