Physical Methods for Determining the Mode of Coordination

The determination of the mode of coordination of chalcogenocyanate ligands is fraught with difficulties. Although various techniques have 

Some Types of Chalcooenocyanate Coordination Confirmed by X-Ray Crystallography 

Both types of monodentate coordination in a single molecule 

Infrared spectra of thiocyanate and related complexes have been thoroughly reviewed by Bailey et al. (57). Because of the importance of this technique for structural assignments, a certain amount of repetition of material included in their review is necessary here, although the retabulation of data already collated has been kept to a minimum. 

A single sharp band at 480 cm has been assigned to the bending mode in an N-bonded complex, in contrast to the several, low-intensity bands near 420 cm observed in jS-thiocyanates (489, 639).
