title: Crystal structure of tetra-aqua-(di-methyl-formamide)-tetra-kis-(μ-N,2-dioxido-benzene-1-carboximidato)tetra-kis-(μ-tri-methyl-acetato)-tetra-manganese(III)sodiumyttrium-di-methyl-formamide-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 [Y(III)Na(OTMA)4[12-MCMn(III)N(shi)-4](H2O)3.76(DMF)0.24·8.04DMF·0.62H2O, where OTMA is tri-methyl-acetate, MC is metallacrown, shi(3-) is salicyl-hydroximate, and DMF is N,N-di-methyl-formamide, is reported. The macrocyclic metallacrown consists of an -[Mn(III)-N-O]4- ring repeat unit, and the metallacrown captures one Y(III) ion and one Na(I) ion in the central cavity on opposite faces of the metallacrown. Overall the metallacrown is domed towards the side of the Na(I) ion. Both the Y(III) and Na(I) ions are eight-coordinate, and the tri-methyl-acetate anions bridge the central Y(III) to each ring Mn(III) ion. The ring Mn(III) ions are six-coordinate with a tetra-gonally distorted octa-hedral geometry.
