The novel complex (1) in which both benzylic nitrogens and heteroaromatic ones to the same metal ion with the rigid ligand imposed by the large heteroaromatic moiety first time was synthesized; a 2: 1 (ligand: metal ions) type complex which has steric resistance and strong thermochemical driving force was obtained. The crystal structures of characteristic ligand (LA4) and complexes (4, 7, 10), in which one cell includes two moieties: there exist minute difference in coordinated bonds and angles despite the same metal ions with the same ligand, were obtained. It shows that several stable conformation in one complex cell.

Some factors to influence the silicon content of hot metal were proposed on the basis of the experiment in the lab: increasing the binary basicity is favorable to desiliconization; the oxide in slag debases the silicon activity and is of great advantage to desiliconization; Al2O3 and SiO2 are disadvantageous to desiliconization, the volatilization content of SiO2 in coke increases with increasing smelting temperature, leading to increase the silicon content of hot metal; the silicon content of hot metal increases with increasing the drip zone's altitude.
