The structure of the title salt, (C5H6BrN2)[ZnCl3(C5H5BrN2)], consists of discrete 2-amino-5-bromo-pyridin-1-ium cations and distorted tetra-hedral (2-amino-5-bromo-pyridine)-tri-chlorido-zincate anions. In the crystal, the complex anions and cations are linked via N-H⋯Cl hydrogen bonds into layers parallel to (101). Short Br⋯Cl contacts of 3.4239 (11) and 3.4503 (12) Å are observed, as well as...

the synthesis of 3-amino-1-nitroguanidine (3-anq) and 5-hydrazino tetrazole (5-ht) derivatives as new energetic materials are described. reaction of 3-anq with triethyl orthoformate leads to the formation of 3-nitramino triazole while no reaction was observed whit 5-ht. addition of nan3 to a mixture of 3-anq and triethyl orthoformate, afforded 1-nitroguanidyl tetrazole in excellent yield. on th...
