The crystal structure of [Mn(salpn)(acetate)]₂(H₂O)₃; the first example of a manganese(<scp>III</scp>) Schiff base polymeric complex containing a dimeric repeat unit [salpn =N,N′-bis(salicylidene)-1,3-diaminopropane]

Abstract

The crystal structure of [Mn(salpn)(OAc)]2(H2O)3 shows it to be a polymeric array, with the Mn(salpn) units bridged by acetate groups in an anti–anti configuration, with three hydrogen-bonded water molecules per monomer; the two ligands per monomer are rotated 180° with respect to each other.
