| الوصف: | Heteronuclear diethylcarbamato complexes of the form ConMg6-n(Et2NCO2)12 were prepared from the isostructural homonuclear precursors Mg6(Et2NCO2)12, 1, and Co6(Et2NCO2)12, 2, via a solvothermal methodology. Two materials were selected for single-crystal X-ray diffraction analysis: Co1.6Mg4.4(Et2NCO2)12 and Co2.7Mg3.3(Et2NCO2)12. Both compounds crystallize in the orthorhombic space group Ccca, as do 1 and 2. The molecular structure is best described as two trinuclear M3 units cross-linked by diethylcarbamate ligands and twisted about one another, so that the complex has overall D2 symmetry and is chiral. Each trinuclear unit consists of two terminal pentacoordinate metal ions and one central hexacoordinate metal ion. The X-ray diffraction data were unambiguous that the Co2+ ions migrate exclusively to the pentacoordinate sites in the heteronuclear complexes, thus demonstrating that metal ion scrambling at the molecular level must occur. The composition of individual crystals can be continuously varied for... |
