Neutron diffraction analysis of (H/sub 3/Pt/sub 2/(Ph/sub 2/PCh/sub 2/CH/sub 2/PPh/sub 2/)/sub 2/)/sup +/(BPh/sub 4/): an unusual example of an unsymmetrical (P/sub 2/Pt(. mu. -H)/sub 2/PtP/sub 2/H) core

An accurate single-crystal neutron diffraction analysis of the compound (H/sub 3/Pt/sub 2/(Ph/sub 2/PCH/sub 2/CH/sub 2/PPh/sub 2/)/sub 2/)/sup +/(BPh/sub 4/)..sqrt.. is reported herein. The large crystal was obtained by the recrystallization of the compound from an acetone/ether mixture. The four coordinated platinum atom was found to have a normal square-planar geometry with interatomic angles close to ideal values. It was noted that the two bridging H atoms were marked by asymmetry of their position. The distances between the atoms are reported. The most accurate measurements of a terminal Pt-H bond distance to date is reported to be 1.610 A, while earlier measurements from x-ray diffraction were reported to be 1.527, 1.66, 1.78, and 1.98 A. 16 references, 1 figure.
