Abstract

As part of an investigation into the chemistry of molybdenum underway at South Dakota State University it became necessary to investigate the possible existence of the linear dioxomolybdenum (VI) (Moo2 2+) moiety. In order to attain this goal, a planar quadradentate chelate of very limited flexibility was necessary. A chelate which satisfied thiscriterion was phthalocyanine. A literature search revealed no evidence of a molybdenum complex containing the linear dioxomolybdenum (VI) group. While molybdenum phthalocyanine complexes had been reported, chemical and physical evidence to substantiate the formulation was limited and in several instances was contradictory. Therefore it was decided to investigate the molybdenum phthalocyanine system in an attempt to resolve the conflicting reports. Since molybdenum can exist in oxidation states from zero to plus six, this research project affords the opportunity to develop procedures for the preparation of a variety of phthalocyanine derivatives. The information attained from these studies also will provide a first step toward the ultimate goal of the isolation of molybdenum porphyrin compounds. This is possible since phthalocyanine is related to porphyrin, the fundamental nucleus of chlorophyll and hemoglobin, and in many instances metal phthalocyanine complexes have served as the basis for biological model system investigations.
