Interaction of 4,4′-bi(1,2,4-triazole) (btr) with copper(II) chloride (bromide) in aqueous or aqueous alcohol media led to a series of coordination polymers featuring the formation of μ 3-hydroxotricopper(II) clusters and their integration into 3D frameworks. These unprecedented structures originate in the propagation of trigonal hydroxotricopper(II) clusters bridged by tri- or tetradentate organic ligands. Complex [{Cu3(μ3-OH)}{Cu3(μ 3-O)}(μ4-btr)3(H2O) 4(OH)2Cl6]Cl·0.5H2O adopts a structure of SrSi2 topology, with eight-fold interpenetration of the coordination frameworks. The structure of [{Cu3(μ 3-OH)}2(μ3-btr)6(μ 4-btr)(μ-X)X4]X5·nH2O (X = Br, n = 6; X = Cl, n = 8) involves 2D coordination layers [{Cu 3(μ3-OH)}(μ3-btr)3] n with an exceptional (3,6)-net topology, which are cross-linked by tetradentate btr ligands and bridging chloride (bromide) ions.

High-nitrogen compound, 3,3′,5,5′-tetraazido-4,4′-bis(1,2,4-triazole) (TABT, 83.99% N), is synthesized from sodium azide and 3,3′,5,5′-tetrabromo-4,4′-bis(1,2,4-triazole) (TBBT) which is prepared by the bromination of 4,4′-bis(1,2,4-triazole) (BTz). It is fully characterized by IR, HRMS, NMR, and single crystal X-ray diffraction showing two triazole rings of TABT perpendicular to each other. DSC and TGA are employed to study TABT's thermal stability with a decomposition temperature at 125.39?°C (onset). The calculated detonation heat of TABT and the predicted detonation velocity are 6449?kJ·kg?1and 8649?m·s?1, respectively. The reduction of TABT with hydrogen and Pd/C gave the stabilized 3,3′,5,5′-tetra(t-butyloxycarbamido)-4,4′-bis(1,2,4-triazole) (11) in the presence of (Boc)2O, providing an alternative path to the high energy density material (HDEM) TNBT [3,3′,5,5′-tetranitro-4,4′-bis(1,2,4-triazole)].

A facile one-step procedure for the preparation of 4,4′-bis-1,2,4- triazole is reported. Direct transamination of N,N-dimethyl-formamide azine dihydrochloride by heating with 4-amino-1,2,4-triazole in refluxing benzene readily yields the target molecule in short duration of time with significant yield (73%). This catalyst-free method was extended to synthesise a series of 4-substituted 1,2,4-triazoles of potential interest in coordination chemistry. Georg Thieme Verlag Stuttgart.
