“…The copper chlorine coordination bonds are much longer (∼2.71 Å) than the Cu–O bonds in the previously described complexes 5 and 10 . This is in agreement to the recently published structure of dichlorido-tetrakis-1,2,4-triazole copper(II), where the Cu–Cl bonds are even longer (2.83 Å) …”

3-Amino-1-nitroguanidine (ANQ, 2) was synthesized via hydrazinolysis of nitroguanidine. By dissolving 2 in solutions containing transition metal salts, several complexes M(2+)(ANQ)2X2(H2O)y with M(2+) = Co, Ni, Cu, Zn as well as M(ANQ)2X(H2O)y with M = Ag could be isolated. In these cases, nitrate as well as perchlorate and chloride served as the respective anions X. Additionally, the ANQ complexes of Co, Ni, and Ag with dinitramide as the anion were synthesized from ANQ and silver dinitramide and by reacting the cobalt and nickel ANQ perchlorate complexes with ammonium dinitramide. The crystal structures of all described complexes were determined by low temperature single-crystal X-ray diffraction. Additionally, they were characterized using IR spectroscopy and elemental analysis. The decomposition temperatures were determined by differential scanning calorimetry and the sensitivities toward impact and friction were assessed using a BAM drophammer and a BAM friction tester (BAM = Bundesanstalt für Materialforschung und -prüfung). Additionally, the sensitivity toward electrostatic discharge was determined on a small-scale ESD device. The potential use of the nitrate, dinitramide and perchlorate containing species as primary explosives was investigated in a laser ignition test.

“…The octahedral copper complex exhibits analogous ligand coordination to that observed in [MCl 2 (TzH) 4 ] (M=Mn, Fe), but with shorter and longer M−N distances (2.0049 and 2.8296 Å) in comparison with [MCl 2 (TzH) 4 ] (M=Mn, Fe). The deviations in the interatomic distances can be explained by the distorted (4+2) coordination octahedron of the copper complex …”

The complexes [MCl2 (TzH)4] (M=Mn (1), Fe (2); TzH=1,2,4-1H-triazole) and [ZnCl2 (TzH)2] (3) have been obtained by mechanochemical reactions of the corresponding divalent metal chloride and 1,2,4-1H-triazole. They were successfully used as precursors for the formation of coordination polymers either by a microwave-assisted reaction or by thermal conversion. For manganese, the conversion directly yielded 1∞ [MnCl2 TzH] (4), whereas for the iron-containing precursor, 1∞ [FeCl2 TzH] (6), was formed via the intermediate coordination polymer 1∞ [FeCl(TzH)2]Cl (5). For cobalt, the isotypic polymer 1∞ [CoCl(TzH)2]Cl (7) was obtained, but exclusively by a microwave-induced reaction directly from CoCl2 . The crystal structures were resolved from single crystals and powders. The dielectric properties were determined and revealed large differences in permittivity between the precursor complexes and the rigid chain-like coordination polymers. Whereas the monomeric complexes exhibit very different dielectric behaviour, depending on the transition metal, from "low-k" to "high-k" with the permittivity ranging from 4.3 to >100 for frequencies of up to 1000 Hz, the coordination polymers and complexes with strong intermolecular interactions are all close to "low-k" materials with very low dielectric constants up to 50 °C. Therefore, the conversion procedures can be used to deliberately influence the dielectric properties from complex to polymer and for different 3d transition-metal ions.
