(b) The square-planar complex trans-[Pt"(H)(CI)(PPh3)2] (structure shown below) is analyzed by means of 'H NMR, 3'P{'H} NMR, 195Pt{'H} NMR, and IR spectroscopy. Php H PPH3 i. Predict the pattern of the peak(s) assigned to: - the hydrido ligand (H) in the 'H NMR spectrum - the phosphorous atoms in the ylp{'H} NMR spectrum - the platinum atom in the 195Pt{'H} NMR spectrum Page 7 of 8 [14 marks) [14 marks) [14 marks] and justify your statements. 'H: I = 1; 100% naturally abundant 31p: I = 1; 100% naturally abundant 195Pt: I = 12; 33.8% naturally abundant Coupling constants: '/('H,195Pt) = 700-1000 Hz; 2/('H,3!P) = 10-15 Hz; '/[3'p,195Pt) = 1000-4000 Hz Ignore the possible occurrence of the 13 satellites. Cl may be regarded as an NMR-inactive nucleus. ii. How many metal-phosphorous stretching bands do you expect to observe in the IR spectrum of the complex? Justify your statement. [8 marks]
