Synthesis and electrochemistry of [Mo(NO){HB(mppz)3}X2](mppz = 3-p-methoxyphenylpyrazolyl, X = CO or Cl); crystal structure of [Mo(NO){HB(mppz)3}(CO)2]
摘要:
The new tripodal ligand K[HB(mppz)3] (mppz = 3-p-methoxyphenylpyrazolyl) and its complexes [Mo(NO){HB(mppz)3}X2] (X = CO or Cl) have been synthesised. The crystal structure of the dicarbonyl complex shows that the molybdenum atom is in an approximately octahedral coordination environment and that the three aryl substituents on the tripodal ligand produce some steric compression of the coligand geometry to give (O)N-Mo-C and C-Mo-C angles in the range 83.7(6)-86.0(6)-degrees as compared to 90.45(30)-degrees for the analogous complex containing the HB(pz)3 (pz = pyrazolyl) ligand.
afforded the aryl hydride [R h(H)(CO)HB(C 3 H 2 N 2 C 6H3OCH3)(C3H2N2C6H4OCH3)2}] (4) by intramolecular cyclometallation involving an ortho CHbond of one p-anisyl substituent. Functionalization of the hydride 4 by chlorinated solvents resulted in the chloro complex [R h(Cl)(CO) HB(C 3 H 2 N 2 C 6H3OCH3)(C3H2N2C6H4OCH3)2}] (5), which maintains the intramolecular ortho Cmetal bond. Evolution of the hydride
