An unexpected 3D (6, 8)-connected metal–organic framework {[Cu5(trz)2(mal)2(fma)(H2O)4]·2H2O}n: Synthesis, structure and catalytic thermodecomposition for ammonium perchlorate

A crystalline 3D MOF {[Cu5(trz)2(mal)2(fma)(H2O)4]·2H2O}n (1) (trz = 1,2,4-triazolate, mal = malate, fma = fumarate) has been synthesized through hydrothermal method and characterized by X-ray crystallography, IR, elemental analysis and thermal gravimetric analysis. The crystal structure revealed that the fma was partly in situ converted into the mal under hydrothermal conditions and the compound was consisted of a 3D (6, 8)-connected honeycomb-like network. Furthermore, the catalytic performance of compound for the thermal decomposition of ammonium perchlorate (AP) was investigated by DSC. The experiment results indicated that the compound accelerated the decomposition of AP.
