Graphical Abstract
In a one-pot reaction from 15 components, a tetra-hedral host-guest compound forms by self-assembly. Its tripod–iron(II) groups are the corners of a tetrahedron (depicted on the right). The edges of the tetrahedron are bridged by 1,2-dinitrile ligands, and a BF
ion is encapsulated in the tetrahedral cavity.
