Notes:
From the reference:
"The nitrosyl groups are less linear in the Rh complex (M-N-O = 158.9 (4)°, vs. 163.5 (10)° for the Ir analog)."
and
"The greater bending of the nitrosyl groups and the longer M-N bonds in the rhodium complex indicate a greater amount of NO⊖ character. The larger N-M-N angle supports this picture. These facts, plus the larger distortion from tetrahedral geometry and the longer nonbonded contacts show that in this environment a rhodium atom shows less tendency to accept electrons (or a greater tendency to donate electrons to ligands) than does an iridium atom. This differs from the usual (and intuitive) picture in which an iridium atom should be more electron rich."
