Two coordination compounds [Pb4(BDT)3(OH) 2(H2O)4]·H2O (1) and [Mn(H2O)6]·(HBDT)2·2H 2O (2) [H2BDT=5,5′-(1,4-phenylene)bis(1H-tetrazole)] had been hydrothermally synthesized. 1 and 2 had been characterized by single-crystal X-ray diffraction, IR, elemental and thermal analyses. Structural analysis reveals that 1 exhibits 2D layer structure extended through BDT with two different coordination modes rings in transverse and vertical. 2 consists of [Mn(H2O)6]2+, free HBDT and water. In addition, 1 and 2 were explored as luminescent materials and additives to promote the thermal decomposition of ammonium perchlorate by differential scanning calorimetry. The temperatures of decomposition for mixture systems of 1/2 with AP, respectively, are both much lower than that of neat AP. Furthermore, the decomposition heats are 1.52 kJ/g and 2.25 kJ/g, respectively, markedly higher than the corresponding value of pure AP. As the additives, 2 (Mn2+) shows much better catalytic activity toward AP decomposition than 1 (Pb2+), which exhibits potential application in the propellants. © 2011 SIOC, CAS, Shanghai & WILEY-VCH Verlag GmbH & Co.
