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

Abstract The alkaline earth metal salts of 5,5′‐BT, [Be(H 2 O) 4 ](5,5′‐BT) · H 2 O ( 1 ), [Mg(H 2 O) 6 (5,5′‐BT) · 3H 2 O ( 2 ), [Ca(H 2 O) 4 (5,5′‐BT)] · H 2 O ( 3 ), [Sr(H 2 O) 4 (5,5′‐BT)] · 2DMF ( 4 ), and [Ba(H 2 O) 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.
