17. -1, R = 0.070 (Rw = 0.098) against 8466 reflections (I ≥ 2σ(I)). Intensity data were collected with a graphite monochromated Mo Kα radiation (λ = 0.71069 Å) on Rigaku AFC5R diffractmeter at 23 °C up to 2θ = 60°(1) and 55°(3), respectively, and corrected for Lorentz polarization effect. The structures were solved by direct methods (SIR 92) for 1 and Patterson method (DIRDIF 92 PATTY) for 3, respectively, and all the non-hydrogen atoms were refined anisotropically except for six fluorine atoms in one of hexafluorophosphate anions in 3 with full-matrix least square technique. The axial site of Rh2 for 1 is weakly coordinated by O2 atom of neighboring molecule (2.599(5) Å). Computational work was carried out by Crystallographic Software package in teXsan.
