Mössbauer Data

Mößbauer spectra of mono and dinuclear iron carbonyl complexes of three cyclic diazenes and the crystal structures of two products formed from (cis-diazene)Fe2(CO)6 and alkynes are reported. The ring size of the diazene ligand influences the stereochemistry of the cycloadducts obtained in the latter reaction; the bicyclic diazaferracycloalkene skeleton of these compounds leads to an exo- and endo-arrangement of one iron carbonyl group relative to the five- and six- membered diazene, rcspectively.
