The structures of MCp (M = Li, Na, K; Cp = cyclopentadienyl), some of
the most important precursors in, synthetic organometallic chemistry,
have been, investigated. All three compounds form polymeric ''multidec
ker structures''. In LiCp and NaCp the metal atoms form a ''string of
pearls'' whereas the potassium atoms in KCp are arranged in a zigzag c
hain that interacts with neighboring chains.
