Rotational barrier of a molybdenum-molybdenum quadruple bond.
نویسندگان
چکیده
The synthesis and characterization of molybdenum(II) porphyrin dimers containing unbridged metal-metal quadruple bonds are presented. Variable temperature 300 MHz (1)H NMR studies of meso-substituted derivatives provide novel solution evidence for both the existence of quadruple bonds and for a barrier to rotation about the metal-metal bonds in these complexes. The activation energy for this rotational process is 10.1 +/- 0.5 kcal.mol(-1).

The formation constants of the species formed in the systems H+ + Mo(VI) + histidine and H+ +histidine have been determined at different aqueous solutions of methanol (0 - 45 % v/v) at 25 °C andconstant ionic strength (0.1 mol dm-3 sodium perchlorate), using a combination of spectrophotometricand potentiometric techniques. The composition of the complex species was determined by thecontinuous v...

terr-Butyl isocyanide cleaves the quadruple metal-metal bonds in Moz(02CMe),, MoZ(OzCCF3),, or K,MozCls to give the mononuclear, seven-coordinate species MO(?-BUNC)~(O~CM~)~ or [Mo(t-B~Nc)~x] [XI, where X is OZCCF3 or C1. These diamagnetic, 18-electron complexes may be converted into the known binary dication [Mo(t-BuNC),] [PF,], by action of NH4PF6 and excess r-BuNC or into the polyoxoanion co...

متن کاملAssessment of molybdenum breakthrough levels in molybdenum-99/technetium-99m generators: One year experience at NIMRA Jamshoro Pakistan
Background: Technetium-99m radioisotope is the backbone of any nuclear medicine institute. This radioisotope is acquired by the elution of Molybdenum-99/Technetium-99m generator which emits 141 keV gamma ray and having 6.04 hour half-life. Occasionally the contents of Molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. This...
