| Abstract: | The platinum complexes Pt(PPh3)2 (PC6F5)2 and Pt(PPh3)2(AsC6F5)2 have been isolated from reactions of Pt(PPh3)3 with (PC6F5)4 and (AsC6F5)4 respectively. A single-crystal X-ray analysis of Pt(PPh3)2(PC6F5)2 has shown that the compound crystallizes in space group P21 with a = 9.286(5), b = 20.95(1), c = 11.226(5) Å, β = 90.7(1)°, Z = 2. The structure has been solved by Patterson and Fourier methods and refined to R = 0.043 from three-dimensional diffractometer data. The complex contains the decafluorophosphorobenzene unit C6F5PPC6F5 bound through each P atom to the platinum. Coordination around the platinum is distorted square planar; the dihedral angle between the two PtP2 planes is 20.4°. |
