Synthesis and crystal structure of a pentacopper(II) 12-metallacrown-4: cis-diaquatetrakis(dimethylformamide-κO)manganese(II) tetrakis(μ3-N,2-dioxidobenzene-1-carboximidate)pentacopper(II) dimethylformamide monosolvate
Abstract:The title compound, [Mn(C3H7NO)4(H2O)2][Cu5(C7H4NO3)4]·C3H7NO or cis-[Mn(H2O)2(DMF)4]{Cu[12-MCCu(II)N(shi)-4]}·DMF, where MC is metallacrown, shi3− is salicylhydroximate, and DMF is N,N-dimethylformamide, crystallizes in the monoclinic space group P21/n. Two crystallographically independent metallacrown anions are present in the structure, and both anions exhibit minor main molecule disorder by an approximate (non-crystallographic) 180° rotation with occupancy ratios of 0.9010 (9) to 0.0990 (9) for one anion a… Show more
