Undervalued N3 coordination revealed in the cisplatin complex with 2'-deoxyadenosine-5'-monophosphate by a combined IRMPD and theoretical study
The complex obtained by the reaction of cisplatin and 2?-deoxyadenosine-5?-monophosphate (5?-dAMP) in water has been isolated and detected by electrospray ionization mass spectrometry. The so-formed cis-[PtCl(NH3)2(5?-dAMP)]+ complex has been studied in detail by infrared multiple photon dissociation (IRMPD) spectroscopy in two spectral ranges, namely, 700–1900 and 2800–3800 cm–1, backed by quantum-chemical calculations at the B3LYP/LACV3P/6-311G** level of theory.
