In the title benzil-idene Schiff base molybdenum(VI) complex, [Mo(C(15)H(12)N(2)O(3))O(2)(CH(3)OH)], the Mo(VI) ion is coordinated by two oxide O atoms and by two O atoms and one N atom of the tridentate N'-(3-meth-oxy-2-oxidobenzyl-idene)benzo-hydrazidate (L) Schiff base ligand. The methanol O atom completes the distorted octa-hedral configuration of the Mo(VI) atom. Strong O-H⋯N hydrogen bond...

The changes in optical and EPR spectra observed during the anaerobic titration of xanthine oxidase with dithionite can be accounted for by simple oxidation-reduction equilibria involving Mo(VI) u MO(V) H Mo(IV); FAD cf FADH. ++ FADH2, and the l-electron reduction of each of the two ironsulfur centers. The equilibrium constants so obtained permit the calculation of the relative probabilities of ...

To the Editor: We read with interest a paper on phospholipid analysis in this journal (1) but deferred comment until the publication of our own paper on the subject, which we believe contains relevant material (2). Sandhu refers to the formation of a Prussian blue complex as the result of a reaction between phospholipids and a chromogenic reagent containing molybdenum. Clearly this cannot be so...

The synthesis of novel biornimetic molybdenum and tungsten compounds that are potential model complexes for molybdenum and tungsten oxidase enzymes is being pursued. Model complexes such as these provide a bener understanding of the basic chemistry of a metal center in an environmeot similar to that found in particular enzyme active sites. This understanding provides a good Starting point [or b...

The title compound, [Mo(2)F(2)O(5)(C(10)H(8)N(2))(2)], is a centrosymmetric binuclear molybdenum(VI) species with the metal atoms in a distorted octa-hedral environment. The coordination geometries of the symmetry-equivalent molybdenum sites are defined by the cis-terminal oxide groups and the N-atom donors of the bipyridyl ligand in the equatorial plane with axial F and bridging O atoms. The b...
