48. 0)]. Structure solution by direct methods located the W and P atoms and several F atoms. All other non-hydrogen atoms were located by alternating least-squares refinement cycles and difference Fourier maps (SHELXTL) and refined anisotropically. All hydrogen atoms except the three hydrides were placed in calculated positions (AFIX). The three hydride atoms were located from the highest peaks near the W atom with W-peak distances ranging from 1.4 to 1.7 A. Their refinement was assisted by restraining the W-H distances to be near 1.70 Å (ADFIX with esd of 0.03 Å). Thermal parameters were allowed to refine freely.
