Two new sodium cytosine compounds, showing an unprecedented coordination of the nucleobase, have been synthesized from aqueous solutions containing perchlorate ions; whereas attempts to obtain similar complexes with Cl-, Br-, NO3-, SO42-, PF6-, (CFSO3-)-S-3 as counterions failed, using sodium tetrafluoroborate a hemiprotonated species, without Na+ cations, was obtained.

Abstract
Two new sodium cytosine compounds, showing an unprecedented coordination of the nucleobase, have been synthesized from aqueous solutions containing perchlorate ions; whereas attempts to obtain similar complexes with Cl-, Br-, NO3-, SO42-, PF6-, (CFSO3-)-S-3 as counterions failed, using sodium tetrafluoroborate a hemiprotonated species, without Na+ cations, was obtained.File in questo prodotto:
