N2 - A family of cationic heavy alkaline earth-metal complexes based on the weakly coordinating tetraphenylborate anion [BPh4]provides unique insight into ion association trends within this family of compounds. The compounds were prepared by protonolysis of the respective alkaline earth-metal bis[bis(trimethylsilyl)]amides M[N(SiMe3)2] 2(thf)2 (M = Ca, Sr, Ba) with ammonium tetra-phenylborates [R3NH][BPh4] (R = Me, Et) in various stoichio-metric ratios, resulting in the separated ions [M(donor)n][BPh 4]2 (M = Ca, Sr, Ba; n = number of donors). All compounds but [Ba(hmpa)6][BPh4]2 (3c) were characterized using single-crystal X-ray diffraction, 1H and 13C NMR, IR spectroscopy and melting point.
