%X The structure of mer-(Pme2Ph)3Cl-cis-H2IrIII (1) has been determined by single-crystal X-ray and neutron diffraction analyses. Crystals are monoclinic, space group P21, with a 11.476(4), b 14.069(5), c 8.286(3)&#506;, &#946; 92.45(1)&#176; and Z 2. Full-matrix least-squares analyses converged 0.022 for 7773 X-ray data and R(F2) = 0.062 for 1538 neutron data. Ir -H [1.557(11)&#506; trans to Cl, 1.603(10) &#506; trans to P] and Ir -P distances [2.292(1)&#506; trans to P, 2.328(1)&#506; trans to H] both exhibit trans lengthening effects. Consistent with the increased hydride content the Ir -P distances in (1) are c. 0.04 &#506; shorter than for the corresponding bonds in its dichloro monohydrido analogues and c. 0.08 &#506; shorter than those in the trichloride . In contrast Ir-Cl [2.505(1)&#506;] is not significantly different to the corresponding distance (2.504 &#506; av.) in mer -(PMe2Ph)3-cis-Cl2HIrIII.
