A wide range of five- and six-coordinate species [Mo O(porph)]+ and irani -[Mo 0(porph)X]° +, where X = OH , alkoxide, halide, H2O, dmso, and so on, were prepared. These complexes have characteristic EPR spectral properties and their electro-, photo-, and catalytic chemistry have been reviewed. Similar phthalocyanine complexes, [Mo(0)(pc)X] (X = Cl, Br, OH) may be prepared by treatment of [MoO(pc)] with FeCb or Br2 or by oxidation of [MoO(pc)] in the presence of OH . Black-pmple [Mo(0)(pc)]l3 was obtained by reaction of 1,2-dicyanobenzene, M0O3, and iodine at 210°, had a square-pyramidal structure, and was paramagnetic (/x = 1.72BM).
