Bi- and oligometallic early and late transition metal complexes based on alkynyl-titanocenes and related species spanned by carbon rich π-systems

The synthesis and reaction chemistry of bi- and oligometallic transition metal complexes containing Groups 4, 8, 10 as well as 11 metal atoms are presented. The respective metals are thereby linked by carbon rich π-conjugated organic units, mainly σ- and π-bonded alkynyls. The structural aspects and electrochemical properties of the corresponding complexes will be discussed.
