The ambidentate thiocyanate ligand (SCN ) can coordinate to a metal centre either through sulfur (SCN)

Question:

The ambidentate thiocyanate ligand (SCN) can coordinate to a metal centre either through sulfur (SCN) or nitrogen (NCS), Chapter 7. Explain the following observed vibrational frequencies for the C–S bond (ν(CS)): K2[Co(SCN)4].4H2O, 850 cm−1; KSCN, 746 cm−1; K2[Pd(SCN)4], 730 cm−1. RbBi(SCN)4 shows an absorption in its IR spectrum at 722 cm−1; what is the likely mode of bonding of the thiocyanate group to bismuth in this compound?
