Description

technical field [0001] The invention relates to an inorganic compound obtained by coordination of a macromolecular ligand and a preparation method thereof, in particular to a 2-[nitrogen-(trityl)imino] with simple operation method, short preparation time and low price Pyridine-2-chromium nitrate compound and its preparation method. Background technique [0002] Due to the inorganic compounds coordinated by macromolecular ligands such as [nitrogen-(trityl)imino]pyridine, they have excellent microporosity, molecular magnetism and linear optics, and have broad application prospects. Therefore, , people pay more and more attention to the study of coordination polymer molecules. For example, in 2006 Fang Yong (Yong Fang, Cui-Ying Huang, Zai-Ming Zhu, Xiao-Li Yu and Wan-Sheng You, Acta Crystallographica Section E, 2006, E62, m3347-3348) et al. reported [nitrogen- (Trityl)imino]pyridine is a cobalt compound synthesized as a ligand, etc. However, due to the large steric hindrance...
