In all those complexes , no matter which conformation ida assumes ( mer - or fac - style ) , the two 0 atoms of 1n2o are both from carboxylic hydroxyl . however , by comparing the bond length , we can find that o ( 4 ) and o ( 2 ) atom is from different group in this complex , 0 ( 4 ) atom from carboxylic hydroxyl , whereas , 0 ( 2 ) from carboxylic carboxide 值得注意的是：在这个双核配合物中，我们首次发现一种新颖的配位方式： ida上与金属离子配位的三齿螯合原子是亚氨n原子、一个羧基上的羟基o原子和另外一个羧基上的羰基o原子。

Researching into tg - dt diagrams , we have concluded as follows : the initial decomposition temperature ( idct ) of polymer ( i ) is 220c and the first lost group ( flg ) ls carboxide ; the idct of polymer ( hi ) is 194cand the flg is - nh ; so the pyrolysis mechanisms of the two polymers are different 对聚合物( d和聚合物( l11 )的tg一ot研究表明:聚合物( d的开始分解温度为220 ，失去的第一个基团为> c = 0 ;聚合物( 11工)的开始分解温度为! 94oc ，先失基团为一阳，两者的热解机理不尽相同。
