Abstract
As a mimic of the oxygen evolution complex in photosystem II, the title manganese(III) complex was synthesized. X-ray structure analysis shows that acetate anions bridge adjacent Mn(III) atoms to form a polymeric chain in the crystal. An anion of the Schiff base, N,N'-bis(salicylidene)-l,3-propyldiamine, coordinates to a Mn(III) atom with an umbrella configuration; the coordination geometry around the Mn(III) atom is flexible.
