The ubiquitous tris(pyrazolyl)borate family of ligands can recognize more than metal cations! Host–guest complexes between elaborated tris(pyrazolyl)borate ligands and protonated amines (see picture) and cationic octahedral metal complexes are described. The latter is an example of an alternative bio-inspired paradigm, in which the guest is preorganized to promote recognition, rather than the host.
