Abstract

In the title complex, [Mn2(C19H20N 2O4)2(C19H22N 2O4)2](PF6)2, the Mn III ion is coordinated by two O [Mn - O = 1.855 (2) and 1.887 (2) Å] and two N [Mn - N = 1.982 (3) and 1.977 (3) Å] atoms from the tetra-dentate Schiff base ligand and a coordinated axial ligand [Mn - O = 2.129 (2) Å]. The centrosymmetric dimer contains two Jahn-Teller-distorted MnIII ions, each in a nearly octa-hedral geometry, connected through two phenolate bridges from two ligands. There are two stereogenic centers. The methyl group and the H atom attached to the middle propane C atom are disordered over two positions with occupancy factors in the ratio 0.58:0.42. The crystal is therefore a mixture of two diasteroisomers, viz. RS/SR and RR/SS. In the axial ligand, the two benzene rings form a dihedral angle of 56.97 (5)° and the dihedral angle between the two MnNC3O chelate rings is 2.98 (12)°
