Summary
This work relates to the mass spectroscopic study of twelve square planar Pt(II) complexes of the general structure {Pt[R2P(CH2)n PR2]X2}, wherein R [dbnd] Me, n [dbnd] 2 (DMPE), n [dbnd] 3 (DMPP); R [dbnd] Et, n [dbnd] 2 (DEPE), n [dbnd] 3 (DEPP); X [dbnd] Cl, Br, I. Results obtained are as follows: (1) the molecular ion is observable in all the spectra, (2) in the region m/e ≥ 194, the peak for the (M-X)+ ion shows maximum intensity, (3) the smallest ion containing a coordination bond observable in all spectra is the (PtP2)+ ion, (4) an appropriate mass spectroscopic fragmentation pattern can be given for ions containing the platinum atom and (5) it is possible to gain information regarding the type of coordination bonds and trans influence of the diphosphine ligands by comparing the percent contribution of certain ions to the total ionization.
