Synthesis and characterisation of some diorganotin bis(N- methyl 0-nitrobenzohydroxamate)
Diorganotin(IV) complexes of N-methyl o-nitrobenzohydroxamic acid were synthesised by refluxing diorganotin(IV) oxide and the free ligand using a Dean and Stark water separator. The N-methyl o-nitrobenzohydroxamic acid was derived from the corresponding o-nitrobenzoyl chloride and Nmethylhydroxylam...

| description | Diorganotin(IV) complexes of N-methyl o-nitrobenzohydroxamic acid were synthesised by refluxing diorganotin(IV) oxide and the free ligand using a Dean and Stark water separator. The N-methyl o-nitrobenzohydroxamic acid was derived from the corresponding o-nitrobenzoyl chloride and Nmethylhydroxylamine in the presence of sodium hydrogen carbonate. The isolated complexes were characterized by elemental analysis and spectroscopic methods such as infrared, lH and 13C nuclear magnetic resonance. Results of analysis carried out on the diorganotin(IV) complexes of N-methyl onitrobenzohydroxamic acid showed a 1:2 stoichiometry with general formula R2Sn[O-NO2C6P4CONCH3O]2 (R= methyl, n-butyl and phenyl). The coordination mode occurs by deprotonation of the hydroxy group and subsequent (0,0) coordination of the carbonyl oxygen. Attempted recrystallization of ndibutyltin(IV) bis(N-methyl o-nitrobenzohydroxamate) from a mixture oftoluene and methanol yielded amorphous solids. |
