Although the general rule for mixed cyclopentadienyl carbonyl complexes is that metals with odd atomic number form mononuclear complexes whilst those of even atomic number form binuclear complexes, it has been reported that mononuclear cyclopentadienyl rhodium dicarbonyl polymerises to a binuclear complex. The structure of a binuclear complex with an unusual carbonyl bridging group is reported.

Ferrocene was the first organometallic guest incorporated and numerous spectroscopic and electrochemical studies have been performed on ferrocene, substituted ferrocene, and related metallocene (e.g. cobaltocene) inclusion complexes (444-469]. Half-sandwich cyclopentadienyl- and benzene-metal carbonyl complexes have also been studied quite extensively [470-479] as have // -allyl metal (palladium) complexes [480], diene metal (rhodium) complexes [481-484], acetylene cobalt carbonyl cluster complexes [485], and complexes with metal carbonyls, e.g. Fe(CO)5, Mn2(CO)io, and CoNO(CO)3 [485a].
