Details of the synthesis and physical properties of (μ-Cl)(μ-pz)[Rh(CO)2]2 are given. Crystals of (μ-chloro) (μ-pyrazolyl)-bis(dicarbonylrhodiumd(I)) are monoclinic, a = 7.0970(8), b = 20.5184(10), c = 15.808(2) Å, β = 94.695(6)°, Z = 8, space group P21/c. The structure was solved by conventional heavy-atom methods and was refined by full-matrix least-squares procedures to R = 0.035 and Rw = 0.038 for 2949 reflections with I ≥ 3σ(I). The complex provides a rare example of molecular stacking in a binuclear transition metal complex with [Formula: see text] distances of 3.5107(8) and 3.6201(8) Å.
