Cyclophosphates as ligands for cobalt(III) in water.
Examination of cyclotriphosphate and cyclotetraphosphate as ligands for Co(III) in aqueous solutions revealed that cyclotetraphosphate affords stable complexes as a hemilabile ligand, while cyclotriphosphate exhibits facile hydrolysis.
Synthesis and characterization of the trimetaphosphate molybdenum tricarbonyl anion [(P3O9)Mo(CO)3]3- as its tris(bis(triphenylphosphine)iminium) salt
Abstract Treatment of ( CH 3 CN ) 3 Mo ( CO ) 3 with the trimetaphosphate salt [ PPN ] 3 [ P 3 O 9 ] · H 2 O ( [ PPN ] + = [ Ph 3 P N- PPh 3 ] + ) (acetonitrile, 25 ° C ) gave the trimetaphosphate-molybdenum complex [ ( P 3 O 9 ) Mo ( CO ) 3 ] 3 - in 91% isolated yield. [ PPN ] 3 [ ( P 3 O 9 ) Mo ( CO ) 3 ] was also obtained in 77% isolated yield by directly treating Mo ( CO ) 6 with [ PPN ] 3 [ P 3 O 9 ] · H 2 O in refluxing acetonitrile, presumably by generating ( CH 3 CN ) 3 Mo ( CO ) 3 in situ . Reported herein is the full characterization and structural determination of [ PPN ] 3 [ ( P 3 O 9 ) Mo ( CO ) 3 ]  and comparison to synthesized and calculated [ ( P 3 O 9 ) M ( CO ) 3 ] n - (M = group 6–9) complexes.
The application of adsorptive stripping voltammetry for a study of the reaction of human serum albumin with anti-human serum albumin
Abstract Adsorptive stripping voltammetry has been used to study the interaction of human serum albumin with anti-human serum albumin. The adsorptive stripping voltammetric behaviour of both proteins has been optimised with respect to accumulation potential, accumulation time and scan rate. It has been demonstrated that adsorptive stripping voltammetry can be a useful technique for the study of the interaction of these two proteins directly in solution.
