固-固化学反应具有一定的优点,在原子簇合成、直接法固相制备化合物等方面已有所表现。研究表明,在溶液中快速进行的连续反应如在固相中进行,速度会降低,而且控制适当的条件可使反应停留在任意一个中间产物上,这在溶液中是难以做到的。基于此,我们用固-固反应制备了M(biN)_xCl_2[I], Solid-solid chemical reaction has certain advantages, in the cluster synthesis, direct solid phase preparation of compounds have been shown. Studies have shown that continuous reactions that progress rapidly in solution, such as in the solid phase, decrease in speed and that controlling the appropriate conditions allows the reaction to stay on either intermediate, which is difficult to achieve in solution. Based on this, we prepared M (biN) _xCl_2 [I] by solid-solid reaction,
