 Reflections were merged by SHELXL according to the crystal
 class for the calculation of statistics and refinement.
 
 _reflns_Friedel_fraction is defined as the number of unique
 Friedel pairs measured divided by the number that would be
 possible theoretically, ignoring centric projections and
 systematic absences.

_refine_special_details          
;

All the hydrogen atoms have been observed in Fourier difference
maps. However, to decrease the number of refined parameters most of them
(those of aromatic ring, methylene groups and those of t-butyl fragment)
have been included in the model in calculated positions and refined
with a riding model.

Several refinement strategies have been tested for hydride ligad.
Its free refinement from observed position leads to unrealistic geometrical
parameters (Si-Ir-H: 64.1 degree angle). Moreover, no evidence of
agostic interactions has been observed in NMR spectra.
Therefore, hydride ligand position has been calculated from consideration of
the molecular geometry and a potential energy minimization calculation
with HYDEX program. Calculated position has been fixed and the isotropic
atomic displacement parameter has been constrained to be 1.5 times the
Ueq of the metal atom.

 All esds (except the esd in the dihedral angle between two l.s. planes)
 are estimated using the full covariance matrix.  The cell esds are taken
 into account individually in the estimation of esds in distances, angles
 and torsion angles; correlations between esds in cell parameters are only
 used when they are defined by crystal symmetry.  An approximate (isotropic)
 treatment of cell esds is used for estimating esds involving l.s. planes.
