Rapid Thermolysis Studies of [Pb2（TNR）2（CHZ）2（H2O）2]·4H2O and Cd（CHZ）2（TNR）（H2O）

T-jump/FT-IR spectroscopy was used to study the rapid thermal decomposition activity of [Pb2（TNR）2（CHZ）2（H2O）2]·4H2O and Cd（CHZ）2（TNR）（H2O） under 0.1 MPa Ar atmosphere. The results show that the main gaseous products of [Pb2（TNR）2（CHZ）2（H2O）2]·4H2O are NH3, H2O and HONO, while CO and NO are the major gaseous products of flash pyrolysis of Cd（CHZ）2（TNR）（H2O）. Thus Cd（CHZ）2（TNR）（H2O） is not an eco-friendly and chemically compatible primary explosive. Both compounds liberate volatile metal carbonate, oxide and isocyanate compounds. The combustion temperature and products of the two compounds were calculated by Real code. The results of theoretical calculation show that the combustion temperature of [Pb2（TNR）2（CHZ）2（H2O）2].4H2O is higher than that of Cd（CHZ）2（TNR）（H2O）, there is no HNCO in the combus- tion products and the amount of NO is less than the experiment result from T-jump/FTIR.     

Synthesis and Structural Characterization of [Mn（phen）2（H2O）2]（OAc）2.6H2O

1 INTRODUCTION Water oxidation to oxygen gas by photo- synthetic apparatus of green plants and cyano- bacteria is the origin of this gas in the atmosphere. The water oxidation center is a tetranuclear, oxide- bridged manganese cluster with O,N-based peri- pheral ligation by amino acid side-chain group[1, 2]. The binding of aqua to the Mn site may be impor- tant to the oxidation of aqua for producing dioxygen. 1,10-Phenanthroline has been adopted to simulate coordination sphere of manga…
