Penta-kis-(μ3-N,2-di-oxido-benzene-1-car-box-imid-ato)di-μ2-formato-penta-kis-(1H-imidazole)-methanolpenta-manganese(III)man-gan-ese(II)-methanol-water (1/3.36/0.65).

ABSTRACT: The title compound, [Mn6(C7H4NO3)5(CHO2)2(C3H4N2)5(CH3OH)]·3.36CH3OH·0.65H2O, or Mn(II)(O2CH)2[15-MCMn(III)N(shi)-5](Im)5(MeOH)·3.36MeOH·0.65H2O (where MC is metallacrown, shi(3-) is salicyl-hydroximate, Im is imidazole and MeOH is methanol), contains five Mn(III) ions as members of the metallacrown ring and an Mn(II) atom bound in the central cavity. The central Mn(II) atom is seven-coordinate with a geometry best described as between face-capped trigonal-prismatic and face-capped octa-hedral. Three Mn(III) ions of the metallacrown ring are six-coordinate with distorted octa-hedral geometries. Of these six-coordinate Mn(III) ions, two have mirror-plane configurations, while the other has a Δ absolute stereoconfiguration. The remaining two Mn(III) ions have a coordination number of five wi
