Reduction of 9,10-bis(trimethylsilyl)anthracene at a sodium metal mirror under aprotic conditions and argon yields its radical anion, which is characterized by its ESR multiplet signal pattern. Crystallizationfrom dimethoxyethane solution under aprotic conditions yields brown prisms of its solvent-separated radical anion salt. The structure, determined in a 130 K cold N2 flow, is discussed in comparison

For over half a century, Mg(anthracene) has been a well-known complex that reacts as a form of “atomic” Mg0, however, heavier alkaline-earth metal anthracene complexes are unknown. Reaction of Ba0 vapour with an anthracene ligand gave a Ba anthracene complex that crystallizes as a cyclic octamer and reacts as a Ba0 synthon.
半个多世纪以来,Mg(蒽)一直是一种众所周知的络合物,它以“原子”Mg 0的形式发生反应,然而,较重的碱土金属蒽络合物尚不清楚。 Ba 0蒸气与蒽配体反应得到Ba蒽络合物,其结晶为环状八聚体并作为Ba 0合成子反应。
