چکیده
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) 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 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)°

The reported structure is a monoclinic polymorph of the title compound, [Mn(2)(C(16)H(14)N(2)O(2))(2)(NCS)(2)], which has been characterized previously in an ortho-rhom-bic form. Each Mn(III) atom is chelated by a tetra-dentate 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate ligand and by the N atom of a thio-cyanate anion, in a square-pyramidal arrangement. The complexes form centro...
