Bis{μ-4,4'-dimeth-oxy-2,2'-[propane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}bis-({4,4'-dimeth-oxy-2,2'-[propane-1,2-diylbis(nitrilo-methyl-idyne)]diphenol}manganese(III)) bis-(hexa-fluorido-phosphate).

In the title complex, [Mn(2)(C(19)H(20)N(2)O(4))(2)(C(19)H(22)N(2)O(4))(2)](PF(6))(2), the Mn(III) ion is coordinated by two O [Mn-O = 1.855†(2) and 1.887†(2)†à ] and two N [Mn-N = 1.982†(3) and 1.977†(3)†à ] atoms from the tetra-dentate Schiff base ligand and a coordinated axial ligand [Mn-O = 2.129†(2)†à ]. The centrosymmetric dimer contains two Jahn-Teller-distorted Mn(III) 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 MnNC(3)O chelate rings is 2.98†(12)°
