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...
