Electronic spectra of some rhodium(III) complexes of saturated cyclic tetramines

Abstract

Rhodium(III) complexes of 12-, 13-, 14-, 15-, and 16-membered saturated cyclic tetramines have been synthesised with Cl^– and PF₆^– as counter ions. Molecular formulae for the complexes have been arrived at on the basis of analytical and conductance studies. The stereochemistry of the complexes has been assigned on the basis of electronic spectral data. It is observed that the rhodium (III) complexes are cis with 12- and 13-, both cis and trans with 14-, and only trans with 15- and 16-membered ring macrocyclic amines.
