Synthesis, structure, and thermal decomposition of two copper coordination compounds [Cu(DAT)2(PA)2] and [Cu(DAT)2(HTNR)2] with nitrogen rich 1,5-diaminotetrazole (DAT)

摘要: Both [Cu(DAT)2(PA)2] (1) and [Cu(DAT)2(HTNR)2] (2) were prepared from 1,5-diaminotetrazole (DAT) copper trinitrophenol, 1 for picrate (PA) 2 styphnate acid (2,4,6-trinitro resorcinol, TNR), characterized by elemental analysis, FT-IR spectroscopy, single crystal X-ray diffraction. The space group of these compounds is P21/c (monoclinic). lattice parameters are similar [a = 11.405(3) A, b = 14.867(3) c = 8.099(2) A a = 12.262(3) A, b = 14.900(3) A, c = 7.243(2) A 2], except the β = 106.257(3)° in β = 92.989(4)° 2. have extended structures due to hydrogen bonds, but there some differences because ligands induced effect. Differential scanning calorimetry analysis shows that two exothermic processes take place both complexes, first peak temperatures 488.2 K 519.2 K kinetic process studied using Kissinger’s method Ozawa’s method, which enthalpy formation...
