Abstract

The title compound 3, is prepared by reaction of [(μ-CO)(η⁵-C₅Me₅)Rh]₂, 1, with N₂=CMe₂, 2. A neutron diffraction study of the structure of 3 at 20 K reveals a normal dimeric structure with approximate C₂ molecular symmetry and a RhRh single bond (2.66 Å). The geometry of the bridging propylidene ligand shows no exceptional features that might be connected with the unusual photolysis behavior of 3, wherein a diamagnetic material with complex ¹H- and ¹³C-NMR spectra is formed. Crystallographic data: a 16.856(3), b 15.978(5), c 18.730(11) Å, β 107.50(2)°, Z = 8, space group P2₁/c (No. 14), R(F²) 0.141 for 8514 neutron data.
