Abstract: The title complex, [Rh(C₇H₅O₂)(C₁₈H₁₅As)(CO)], has a distorted square-planar geometry. The most important bond distances and angles include Rh-C = 1.788 (10) Å, Rh-O(trans to CO) = 2.039 (6) Å, Rh-O(trans to As) = 2.059 (6) Å, Rh-As = 2.3507 (13) Å, O-Rh-O = 78.1 (2)° and O-C-C-O = 3.4 (12)°. The short interplanar distances between the tropolonate ligands [3.57 (5) Å] and phenyl groups [3.51 (5) Å] of neighbouring molecules indicate - stacking interactions, which stabilize the crystal packing.
