An anion is encapsulated in the center of the new cage compound [Ni 6 (atu) 8 X]X 3 (X=Cl—for the structure see picture—or Br; Hatu=amidinothiourea). A combination of Lewis acid–base and hydrogen‐bonding interactions cause the square‐planar [Ni(Hatu) 2 ] 2+ units, after deprotonation, to assemble to form this compound. A remarkable feature is the anion dependence of the cage formation; nitrate, acetate, and perchlorate are unsuitable as templates.
