Abstract

An anion is encapsulated in the center of the new cage compound [Ni<sub>6</sub> (atu)<sub>8</sub> X]X<sub>3</sub> (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)<sub>2</sub> ]<sup>2+</sup> 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.
