Abstract

AbstractThe 31P CP/MAS NMR spectrum of cis‐[PtCl2(PPh2 nPr)(BzS{O}Bz)] was found to exhibit two central resonances with appropriate couplings to 195Pt, despite the fact that a single‐crystal x‐ray diffraction study indicated that the complex crystallized in the monoclinic space group P21/n with Z = 4, i.e. that there is only a single crystallographically unique phosphorus atom. The possibility that the 21 screw axis was absent (i.e. that the space group was actually Pn) was examined by a reinvestigation of the original x‐ray data, but no definitive evidence for the alternative space group could be obtained. An examination of a bulk sample of cis‐ [PtCl2(PPh2nPr)(BzS{O}Bz)] by x‐ray powder diffraction and comparison of the results with data from the single‐crystal x‐ray diffraction experiment revealed that the crystal selected for diffraction studies was a different polymorph from the bulk of the sample which was used for the 31P CP/MAS NMR measurements. X‐ray powder diffraction is thus shown to provide a valuable bridge between solid‐state CP/MAS NMR measurements and single‐crystal x‐ray diffraction data.
