Compounds 1–3 were characterized by spectroscopic studies (NMR, IR) and compounds 1 and 3 were further characterized by single-crystal XRD studies. The pentaborate salts compounds show extensively H-bonded supramolecular anionic lattices which are templated by the cations. Thermal analysis (TGA) of 1–3 showed that thermally decomposed in air at 1000° to B2O3 in a two step process involving dehydration (
