Alkaline Earth Metal Salts of 5,5′‐Bistetrazole – from Academical Interest to Practical Application

The alkaline earth metal salts of 5,5′‐BT, [Be(H2O)4](5,5′‐BT)·H2O (1), [Mg(H2O)6(5,5′‐BT)·3H2O (2), [Ca(H2O)4(5,5′‐BT)]·H2O (3), [Sr(H2O)4(5,5′‐BT)]·2DMF (4), and [Ba(H2O)4(5,5′‐BT)] (5) were fully characterized by low temperature X‐ray diffraction, vibrational (IR, Raman) and NMR spectroscopy, elemental analysis and differential scanning calorimetry (DSC). A detailed description of the crystal structures is given. In addition, the potential use of 4 and 5 in coloring pyrotechnical compositions was investigated.
