FTIR assignments for ligands and complexes.

Compound	C-O (cm^−1)	Ar-N (cm^−1)	C=C (cm^−1)	C-H (cm^−1)	N-H (cm^−1)
DPA	—	1477	1529	3019	3179–3253
2BUT (1)	1230	1476	1508	2926	—
[Ru2(2BUT)(DMF)2(DPA)](BH4)4(3)	1244	1434	1504	2961	—
[Ru2(2BUT)(Cl6] (4)	1245	1435	1508	2948	—

The vibrational spectroscopic data indicated all the functional groups for the ligands and the complexes. Also, it was seen that the ligand functional groups bound by the metal demonstrated a shift in the vibrational frequency, and this indicated that there is coordination.
