| Abstract: | Redox reactions of (L1,2Mg)2] and Sb2R4 (R=Me, Et) yielded the first Mg‐substituted realgar‐type Sb8 polystibides (L1,2Mg)4(μ4,η2:2:2:2‐Sb8)] (L1=HCC(Me)N(2,4,6‐Me3C6H2)]2, L2=HCC(Me)N(2,6‐i‐Pr2C6H3)]2). Compounds (L1,2Mg)2] serve both as reducing agents, initiating the cleavage of the Sb?C bonds, and as stabilizers for the resulting Sb8 polyanion. The polystibides were characterized by NMR and IR spectroscopies, elemental analysis, and X‐ray structure analysis. In addition, results from quantum chemical calculations are presented. |
