A novel metal binding mode of cytosine nucleobases: N(3),N(4) chelation
Abstract
The formation and crystal structure of the first example of an anionic 1-methylcytosine [deprotonated at the exocyclic amino group N(4)] acting as a chelating lilgand for trans-(NH3)2PtIV through N(3) and N(4), trans,trans-diamminebis(1-methylcytosinato) platinum(IV) dinitrate, is reported.
