The crystal and molecular structure of tetrakistriphenylphosphinerhodium(I) hydride

Abstract

Crystals of tetrakistriphenylphosphinerhodium(I) hydride, (Ph₃P)₄HRh^I.½C₆H₆, are isometric, spacegroup T_h⁶–Pa3, a= 2284·5(1) pm, Z= 8: the rhodium atom and one phosphorus atom lie on a three-fold axis, the arrangement of the four phosphorus atoms being regularly tetrahedral to within experimental error, and, though the position of the hydrogen atom has not been determined in this analysis, to be consistent with the crystal symmetry, the hydrogen atom must also lie on the three-fold axis.
