Cole Seager Butler University
Faculty Sponsor(s): Stacy O'Reilly Butler UniversityA series of known and new seven coordinate molybdenum and tungsten complexes of tris(pyrazolyl)methane (Tpm) and substituted Tpm,
[TpmM(CO) X] , have been synthesized. Depending on the identity X, iodo, bromo or hydrido and substitution of the Tpm ligand, substantial chemical shift differences are observed for the hydrogen on the central carbon of the Tpm ligand. Factors impacting the chemical shift of the hydrogen on the central carbon of the Tpm ligand such as the electron donating ability of the Tpm ligand and the electronegativity of the additional ligand on the metal will be discussed.
