Abstract

The metallacrown complex MnII(OAc)2[15-MCMnIII(N)shi-5](Im)3(EtOH)3 has been synthesized and characterized by single-crystal X-ray diffraction and infrared spectroscopy. The compound crystallizes in the monoclinic space group P21/c with a = 24.3326(15) Å, b = 24.0354(15) Å, c = 27.0531(17) Å, α = 90.00°, β = 100.3883(11)°, γ = 90.00°, V = 15562.5(17) Å3, Z = 4, and Z′ = 2. Four of the five manganese(III) ions of the metallacrown ring adopt a distorted octahedral coordination geometry, and the fifth manganese(III) ion is five coordinate and exhibits a distorted square pyramidal environment. The configuration of the manganese(III) ions about the ring follows a pattern of ΔΛΔPP, with P representing planar. In addition, the imidazole units are bound to three separate ring manganese(III) ions, and the imidazole units are directed to the outside of the molecule. A manganese(II) ion is encapsulated in the central core of the molecule, and the central ion is seven coordinate with a face-capped trigonal prismatic geometry.
