Abstract

A 'missing' member of the inverse crown ether family, namely mu(4)-oxo-tetrakis(mu-2,2,6,6-tetramethylpiperidinido)dimagnesium(II)disodium(I), [Na2Mg2O(C9H18N)(4)], has been synthesized by blocking the alternative aromatic metallation route via the use of sterically hindered 1,3,5-mesitylene as a solvent. [Na2Mg2O(NR2)(4)] (NR2 is 2,2,6,6-tetramethylpiperidinide) is shown to form a cationic planar eight-membered ring with alternating metal and N atoms, which captures at its core an oxide guest that lies on an inversion centre [principal dimensions: Na - O = 2.2405 (11) Angstrom, Na - N = 2.445 (3) and 2.572 (3) Angstrom, Mg - O = 1.8673 (9) Angstrom, and Mg - N = 2.032 (2) and 2.063 (2) Angstrom].
