摘　　要：A new large conjugated ligand 1′,8′-diaza-anthreceno-\-1,10-phenanthroline(dap) and its Fe(Ⅱ) complex have been synthesized from phenanthroline and 2,3-diaminonphthalene. The structures and properties of the ligand and the complex were characterized by elemental analysis, IR, MS, UV-vis spectrometry. The study of magnetic susceptibility of the complex indicated the complex lies mainly in low spin state between 80～300 K, while a spin crossover occurs in high temperature region as a result of the stronger ligand field of this ligand than those of dipyrido\[3,2-a:2′phenazine and dipyrazine\,3′h\]quinoxaline.A new large conjugated ligand 1′,8′-diaza-anthreceno-\-1,10-phenanthroline(dap) and its Fe(Ⅱ) complex have been synthesized from phenanthroline and 2,3-diaminonphthalene.
