Abstract: The ¹H、¹³C and ³¹P NMR spectra of platinum complexes (1)and (2)have been measured. The analysis of 1D NMR spectra of complex (2)indicates that it is not[Pt(3-MBPA)₂], but[Pt(3-MBPAH) (3-MBPA) Cl].The ¹H-¹H COSY and ¹H-¹³C HMQC 2D NMR techniques were used to analyze and assign the ¹H and ¹³C NMR spectra of platinum complex trans-[Pt(3-M BPAH)₂Cl₂] (1)and trans-[Pt(3-MBPA) (3-MBPAH) Cl] (2). The trans geometry of the complex has been determined by means of the coupling constants (¹J_P-Pt, ²J_P-P)
