【Abstract】 The \{\}\+1H、\{\}\+\{13\}C and \{\}\+\{31\}P 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-\+\{13\}C HMQC 2D NMR techniques were used to analyze and assign the \{\}\+1H and \{\}\+\{13\}C NMR spectra of platinum complex trans-\[Pt(3-MBPAH)\-2Cl\-2\] (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\}). \;更多还原
