Di-μ-acetato-bis­(dimethyl­formamide)­penta­kis­(μ-N2-dioxidobenzene-1-car­boximidato)tetra­kis­(1-ethyl­imidazole)­penta­manganese(III)­manganese(II)–diethyl ether–dimethyl­foramide–methanol–water (1/1/1/1/0.12)

摘要

The title compound [Mn6(C7H4NO3)5(CH3CO2)2(C5H8N2)4(C3H7NO)2]·(C2H₅)₂O·C₃H₇NO·CH₃OH·0.12H₂O, abbreviated as Mn^II(OAc)₂[15-MC_MnIII(N)shi-5](EtIm)4(DMF)2·diethyl ether·DMF·MeOH·0.12H₂O (where ⁻OAc is acetate, MC is metallacrown, shi³⁻ is salicylhydroximate, EtIM is n-ethylimidazole, DMF is N,N-dimethylformamide, and MeOH is methanol) contains five Mn^III ions as members of the metallacrown ring and an Mn^II ion bound in the central cavity. The central Mn^II ion is seven-coordinate with a distorted face-capped trigonal–prismatic geometry. The five Mn^III ions of the metallacrown ring are six-coordinate with distorted octa­hedral geometries. The configuration of the Mn^III ions about the metallacrown ring follow a ΔΛΔPP pattern, with P representing planar. The four 1-ethyl­imidazole ligands are bound to four different Mn^III ions. A diethyl ether solvent mol­ecule was found to be disordered over two mutually exclusive sites with an occupancy ratio of 0.568 (7):0.432 (7). A methanol solvent mol­ecule was found to be disordered over two mutually exclusive sites by being hydrogen bonded either to a dimethyl­formamide solvent mol­ecule (major occupancy component) or to an O atom of the main mol­ecule (minor occupancy component). The occupancy ratio refined to 0.678 (11):0.322 (11). Associated with the minor component is a partially occupied water mol­ecule [total occupancy 0.124 (15)].
