The reaction of the cyclic amines 1,5-diazobicyclo[4.3.0]non-5-ene (DBN), 1,8-diazobicyclo[5.4.0]undec-7-ene (DBU) and 1,8-bis(dimethylamino)naphthalene (PS) with B(OH)3 in a 1:5 ratio affords in high yields the non-metal cation pentaborate salts [HDBN][B5O6(OH)4] (1), [HDBU][B5O6(OH)4] (2) and [HPS][B5O6(OH)4]·B(OH)3 (3). 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 (
