[Sb12{(2-MeO)C6H4N}18]·6 THF; A Twenty-Four Membered Imidoantimony(III) Metallacycle

Six Sb2N2 rings linked by single imido–N bridges to give a 24-membered ring characterize the structure of the title compound (the core is shown on the right). This is the largest Group 15 metal–imido complex to be structurally characterized and the first p block metal–imido metallacycle.
