PREPARATION AND STRUCTURE OF A QUADRUPLY BONDED DI-MOLYBDENUM COMPOUND CONTAINING 7-AZAINDOLYL LIGAND

The reaction of 7-azaindole with Mo2Cl4(PEt3)4 gives a 29% yield of emerald green Mo2Cl2(PEt3)2(C7H5N2)2. The compound has been characterized by x-ray crystallography. It crystallizes in space group[Formulla Omitted] The molecules lie on crystallographic inversion centers, and the ligand arrangement is such that there is no additional molecular symmetry possible. Thus, the Mo2P2Cl2 atoms are coplanar and the two azaindolyl groups lie above and below this plane oriented in opposite directions. The Mo-Mo distance is 2.125 (1) Å and all other distances are normal. There is some disorder in the PEt3 group. © 1978, American Chemical Society. All rights reserved.
