Crystal structure of tetraaqua(dimethylformamide)tetrakis(μ-N,2-dioxidobenzene-1-carboximidato)tetrakis(μ-trimethylacetato)tetramanganese(III)sodiumyttrium-dimethylformamide-water (1/8.04/0.62)

Abstract

The synthesis and crystal structure for the title compound, [YNaMn4(C7H4NO3)4(C5H9O2)4(H2O)3.76(C3H7NO)0.24]·8.04C3H7NO·0.62H2O or [YIIINa(OTMA)4 [12-MCMn(III)N(shi)-4](H2O)3.76 (DMF)0.24·8.04DMF·0.62H2O, where OTMA is trimethylacetate, MC is metallacrown, shi3- is salicylhydroximate, and DMF is N,N-dimethylformamide, is reported. The macrocyclic metallacrown consists of an -[MnIII-N-O]4- ring repeat unit, and the metallacrown captures one YIII ion and one NaI ion in the central cavity on opposite faces of the metallacrown. Overall the metallacrown is domed towards the side of the NaI ion. Both the YIII and NaI ions are eight-coordinate, and the trimethylacetate anions bridge the central YIII to each ring MnIII ion. The ring MnIII ions are six-coordinate with a tetragonally distorted octahedral geometry.
