INTRODUCTION. The complexes of rare-earth metal with sulphoxides are a class of compounds that possess properties of extraction, catalysis and luminescence. It would be condutive to understanding the relationship between structure an4 property to clarify the influenece of lanthanide contraction and sulphoxide ligands with differe(?) substitution groups upon coordination geometry and neighbouring environment of rare-earth ion. We are carrying out systematic investigations of lanthanide complexes with dibenzyl sulphoxide(DBSO). The structure of La(NO_3)_3·(DBSO)3·CH_3OH reported herein is a part of our studies.
