Abstract
Recently, the demand for new renewable and sustainable polymers, as well as their use as precursors to produce energetic materials, has emerged as a popular and burgeoning area of study. In this study, novel energetic nitrogen-rich polymers based on the 1,3,5-triazine ring were synthesized utilizing standard techniques. Four monomers were created initially: 4,6-dichloro-N-(4-chlorophenyl)-1,3,5-triazine-2-amine (A), 1,1’-bis(4,6-dichloro-1,3,5-triazine-2-yl)-1 H,1’H-5,5’-bitetrazole (B), 2,4,6-trihydrazinyl-1,3,5-triazine (C), N-(4-chlorophenyl)-4,6-dihydrazinyl-1,3,5-triazin-2-amine (D) In the second step, seven novel polymers named CHTA, TBT, TBTH, CTBT, THT, CTC, and TCT were synthesized via polyaddition reactions with monomers. Infra-red spectroscopy was used to characterize the nitrogen-rich polymers that were formed (IR). TGA measurements were utilized to investigate the thermal stability of substances. In addition, SEM and 1HNMR were utilized to describe the compounds. The results of thermal analysis indicate that TBT, CTC, and TCT are less stable than other nitrogen-rich polymers. The reaction yield for synthesized energetic polymer were 73%, 92%, 67%, 80%, 84%, 72%and 74%for CHTA, TBT, TBTH, CTBT, THT, CTC and TCT respectively.

Abstract
The title compound, C20H22N8O2, was synthesized by the coupling reaction of a sodium tetra-zolate salt and di-bromo-butane in a molar ratio of 2:1. The reaction can produce several possible regioisomers and the title compound was separated as the major product. The X-ray crystallographic study confirmed that the title compound crystallizes in the monoclinic P21/c space group and possesses a bridging butyl-ene group that connects two identical phenyl tetra-zole moieties. The butyl-ene group is attached not to the first but the second nitro-gen atoms of both tetra-zole rings. The dihedral angles between the phenyl groups and the adjacent tetra-zolyl rings are 5.32 (6) and 15.37 (7)°. In the crystal, the mol-ecules form centrosymmetric dimers through C-H⋯O hydrogen bonds between a C-H group of the butyl-ene linker and the O atom of a meth-oxy group.

Abstract
1-(5-Amino-3-azapentyl)tetrazole dihydrochloride (HL·2HCl) was prepared by heterocyclization of diethylenetriamine with triethyl orthoformate and sodium azide followed by treatment with potassium carbonate and hydrochloric acid. The reaction of CuCl2, HL·2HCl and triethylamine (NEt3) in a molar ratio of 1 : 1 : 3 in water was found to generate a novel organometallic tetrazole derivative Cu2L2Cl2. This compound is present as a binuclear centrosymmetric molecular complex, in which C-deprotonated tetrazole L acts as a chelating ligand via the two amino N and tetrazole ring C coordination sites and the two copper atoms are linked together through two tetrazole ring N(4)-C(5) bridges. This complex is the first organocopper tetrazole derivative. When the molar ratio of the reagents in the abovementioned reaction was changed to 1 : 2 : 2, the complex Cu(HL)2Cl2 was formed along with Cu2L2Cl2. Pure Cu(HL)2Cl2 was isolated after reaction of the reagents in a molar ratio of 1 : 3 : 6. The complex Cu(HL)2Cl2 is present as a mononuclear molecular complex, with a chelating coordination mode of HL via the two amino N atoms only. Both complexes as well as HL·2HCl were characterized by single-crystal X-ray analysis.
