    • Intensity data of 1 were collected at 293 K on a Rigaku Saturn 70 CCD diffractometer using graphite-monochromated Mo Kα radiation (λ, 0.710 73 Å, The structure was solved by direct methods and refined by full-matrix least squares on F2 using the SHELXTL-97 program package. Routine Lorentz and polarization corrections and empirical absorption correction were applied. P4, P5, and P6 atoms were disordered over two positions; Fe8 and Fe9 atoms were also disordered with an occupancy of 0.25 for each.
