A reductive cyclisationreaction occurs when complexes of the type [Mo(η-C5H5)(CO)2I(L)](L is a halogen-substituted tertiary arsine) react with sodium amalgam in tetrahydrofuran giving cyclic molybdenum–arsine complexes. The stereochemical non-rigidity of the ring systems in solution has been interpreted in terms of a square-pyramidal–trigonal-bipyramidal isomerisation process. The cyclic complex dicarbonyl
