摘要：

Packed in like sardines: Three BF 4 - ions are packed into the three cavities of an interpenetrated dimer of a coordination cage (see scheme). While the inner BF 4 - ion is tightly bound inside the central position, the loosely bound outer anions can be replaced with halide anions by an allosteric binding mechanism and a concerted structural change. In particular, Cl - is bound with great affinity. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
