Structural studies of matrix-isolated alkali metal chlorates; an example of tridentate co-ordination by the chlorate ion

Abstract

The vapours from heated alkali metal chlorates isolated in nitrogen and argon matrices have been studied by infrared spectroscopy. The use of ¹⁶O–¹⁸O partial isotopic substitution demonstrates the presence of a C₃ axis for the molecule CsClO₃ isolated in an argon matrix. This is interpreted as the ClO₃^– ion showing a tridentate interaction with the caesium ion.
