Deprotonation of indene followed by addition of Ph2PCl yields one isomer of Ph2PC9H7 (1a) which, on standing, converts to a second (1b). The crystal structure of 1b has been determined and reveals that the diphenylphoephino group is attached to an sp2 carbon of the five-membered ring. The compound crystallizes in the monoclinic space group P21/c with a = 8.214 (2) ?, b = 16.651 (7) ?, c = 11.970 (4) ?, β = 93.37 (2)°, V = 1634.3 (10) ?3, and Z = 4. Least squares refinement converged at R = 0.0456 and Rw = 0.0415 based on 3280 reflections with F > 4.0σ(F). A series of platinum complexes of the type [PtClxMeyL2] (x + y = 2) has been isolated for each isomer. In the complexes of 1a the presence of a chiral carbon in the Ph2PC9H7 ligands results in the formation of two pairs of diastereomers, which could be distinguished by NMR spectroscopy.
