N2  - The structure of the novel mixed-phosphine complex mer(PMe3)-trans(PEt3)(PPri3)H-trans-Cl2IrIII has been determined by single-crystal X-ray diffraction analysis at 146&#177;3 K. Crystals are monoclinic, space group P 21/c, with a 7&#183;414(4), b 15&#183;073(3), c 9&#183;796(2) &#197;, &#946; 97&#183;46(1) and Z 4. Structure refinement by constrained (2xC-C distances) full-matrix least-squares analysis (2378 unique reflections, 217 parameters) converged with R 0&#183;049 and &#x03C9;R 0&#183;055. The PPri3 ligand is face-to-face configured with the unique Pri group eclipsing the hydride ligand. The PEt3 ligand is asymmetrically configured with Ir-P-C-C torsion angles 174, &#8211;72 and &#8211;146&#176;. Metal&#123;ligand distances are: Ir&#123;P(1,2,3) 2&#183;366(4), 2&#183;372(4), 2&#183;306(4) &#197;; Ir-Cl(1,2) 2&#183;386(4), 2&#183;372(4) &#197;. The P-Ir-P(trans) angle is 157&#183;2(1)&#176;.
