| 摘 要： | The σ bond is an important concept in chemistry, and the metal–carbon(M–C) σ bond in particular is a central feature in organometallic chemistry. Synthesis of stable complexes with five coplanar M–C σ bonds is challenging. Here, we describe the synthesis of two different types of stable complexes with five coplanar M–C σ bonds, and examine the stability of such complexes which use rigid conjugated carbon chains to chelate with the metal center. Density functional theory(DFT) calculations show th...
