Inside out approach : Twofold deprotonation of benzene by a sodium monoalkyl bisamido manganate(II) reagent derived from BuNa, 2,2,6,6‐tetramethylpiperidine, and Mn(CH 2 SiMe 3 ) 2 has produced the first inverse‐crown complex in which the transition‐metal atoms are incorporated in the host (see X‐ray structure, blue N, green Na, purple Mn). Variable‐temperature magnetization measurements show that the complex is antiferromagnetic.
