Abstract

A new neutral triazole-based N-heterocyclic carbene rhodium(I) complex [RhCl(C₈H₁₂)(C₈H₁₅N₃)], has been synthesized and structurally characterized. The complex crystallizes with two mol-ecules in the asymmetric unit. The central rhodium(I) atom has a distorted square-planar coordination environment, formed by a cyclo-octa-1,5-diene (COD) ligand, an N-heterocyclic carbene (NHC) ligand, and a chlorido ligand. The bond lengths are unexceptional. A weak inter-molecular non-standard hydrogen-bonding inter-action exists between the chlorido and NHC ligands.

Keywords: N-heterocyclic carbenes; crystal structure; neutral transition-metal complexes; rhodium.
