(Carbazol-9-ido-κ N )di-chlorido-(η 5 :η 1 -2,3,4,5-tetra-methyl-penta-fulvene)tantalum(V).

The reaction of (η 5 :η 1 -2,3,4,5-tetra-methyl-penta-fulvene)tantalum(V) dicarbazolide chloride ( 1 ) with etheric HCl results in the formation of the title compound ( 2 ), [Ta(C 10 H 14 )(C 12 H 8 N)Cl 2 ]. The Ta V atom has a distorted tetra-hedral coordination environment in a three-legged piano-stool fashion. The conformation of the penta-fulvene exocyclic C atom to the three other ligands is staggered and not eclipsed, as found in the crystal structure of 1 . Inter-molecular inter-actions include π-π stacking, H⋯π inter-actions and weak C-H⋯Cl hydrogen bonds.
