Xiao-Ye Wang,Marcus Richter,Yuanqin He,Jonas Björk,Alexander Riss,Raju Rajesh,Manuela Garnica,Felix Hennersdorf,Jan J. Weigand,Akimitsu Narita,Reinhard Berger,Xinliang Feng,Willi Auwärter,Johannes V. Barth,Carlos-Andres Palma,Klaus Müllen +15 more
TL;DR: In this paper, azomethine ylide homocoupling is used to insert an antiaromatic pyrazine ring into the core of a nanographene, and characterize the molecule's unique electronic character.
Journal ArticleDOI
Derivatives of 1,5-diamino-1H-tetrazole: a new family of energetic heterocyclic-based salts.
Juan Carlos Gálvez-Ruiz,Gerhard Holl,Konstantin Karaghiosoff,Thomas M. Klapötke,Karolin Löhnwitz,Peter Mayer,Heinrich Nöth,Kurt Polborn,Christoph J. Rohbogner,Max Suter,Jan J. Weigand +10 more
TL;DR: In this paper, a new synthesis for 1,5-diamino-1H-tetrazolium nitrate (2a) and perchlorate (2b) was introduced that avoids lead azide as a hazardous byproduct.
Journal ArticleDOI
1,5-Diamino-4-methyltetrazolium dinitramide
TL;DR: The highly friction-sensitive 1,5-diamino-4-methyltetrazolium dinitramide was synthesized by a metathetical reaction of the corresponding iodide and silver dinitramside, and the chemical bond is discussed on the basis of the theory of atoms in molecules (AIM).
Journal ArticleDOI
Azidoformamidinium and Guanidinium 5,5‘-Azotetrazolate Salts
Anton Hammerl,Michael A. Hiskey,Gerhard Holl,Thomas M. Klapötke,Kurt Polborn,Jörg Stierstorfer,Jan J. Weigand +6 more
TL;DR: In this article, the authors investigated the energy properties of the 5,5‘-azotetrazolate anion with different guandidinium cations and obtained the crystal structures of AFZT and AGZTH, which crystallize in the monoclinic space groups P21/n and C2/c.
Journal ArticleDOI
BTA copper complexes.
Manfred Friedrich,Juan Carlos Gálvez-Ruiz,Thomas M. Klapötke,Peter Mayer,Birgit Weber,Jan J. Weigand +5 more
TL;DR: The reaction of Cu(2+) ions in aqueous ammonia solution with bis(tetrazolyl)amine (H(2)bta) was investigated and three complexes were obtained; some physicochemical properties of these complexes with respect to high-energetic materials are discussed.
