bridges, generating an unusual 2Dlayer, in which [M3(μ3-X)] triangular motifs act as three-connecting nodes and the mononuclearmotifs acting as six-connecting nodes that are inter-linked by the ligands. The 2Dlayer in 1 and 3 represents a novel type of a geometrically spin-frustrated lattice. Both 4 and 5 consist of co-crystallized binuclear motifs and 1Dpolymericchainmotifs, which arise from two different

The present invention provides Bis-(1(2)H-tetrazol-5-YL)-amine compound, and safe and inexpensive methods for producing high quality Bis-(1(2)H-tetrazol-5-YL)-amine compound. Also provided are Bis-(1(2)H-tetrazol-5-YL)-amine intermediates, and methods for their preparation. The process of preparing Bis-(1(2)H-tetrazol-5-YL)-amine intermediate substantially combines dicyanamide salt, azide salt, solvent and acid at 40-70 C temperature. The process of preparing Bis-(1(2)H-tetrazol-5-YL)-amine anhydride and/or Bis-(1(2)H-tetrazol-5-YL)-amine monohydrate comprises heating the intermediate described above at ≧75 C and adding a second acid.

the reaction of Cu(2+) ions in aqueous ammonia solution with bis(tetrazolyl)amine (H(2)bta) was investigated. Depending on the reaction conditions three complexes were obtained: Cu(bta)(NH(3))(2) (1), Cu(bta)(NH(3))(2).H(2)O (2), and (NH(4))(2)Cu(bta)(2).2.5H(2)O (3). The crystal structures of 1 and 2 are discussed with respect to the coordination mode of the dianion of N,N-bis(1(2)H-tetrazol-5-yl)-amine

Three new lead(II) N,N-bis[1(2)H-tetrazol-5-yl]amine (H2bta) compounds, [Pb(bta)(H2O)2]n (1), [Pb2(bta)2(bpy)2] (2), and [Pb2(bta)2(phen)2]·2H2O (3), were synthesized. Single-crystal X-ray diffraction reveals that compound 1 has a 1D polymeric zigzag chain structure, whereas compounds2 and 3 have binuclear structures. In addition, compounds 1–3 were explored as additives to promote the thermal decomposition
short reaction times is a new method in organic chemistry. A N-rich Cu-MOF catalyst, [Cu(BTA)], with -bis(1(2)-tetrazol-5-yl)amine (BTA) ligand has been prepared and characterized using FT-IR, XRD, SEM, EDX, and ICP-AES techniques to investigate its performance as a recyclable catalyst in aldehyde-alkyne-amine (A) coupling reaction for the synthesis of propargylamine derivatives. This catalytic system
