From Homonuclear Metal String Complexes
to Heteronuclear Metal String Complexes
The study of metal string complexes with 1-D transition metal frameworks
began in the early 1990s. Since these complexes provide great insight
into multiple metal-metal bonds, and may have potential applications as
molecular wires, this field of research has grown in the past 20 years.
As such, the electronic structure of the simplest trinuclear complexes,
the supporting ligand systems, and single molecular conductance of metal
string complexes are discussed. This review will introduce the
development of this field and summarize some important results in the
newly designed heteronuclear metal string complexes (HMSCs). These
molecules may be of great interest in studying the nature of
heterometallic electronic effects and molecular electronic applications.
