The crystal and molecular structure of bromo(pi-allyl)cytidine palladi
um(II) has been determined by X-ray diffraction analysis. In this comp
lex, cytidine coordinates to palladium(II) through N-3. The pi-allyl m
oiety is coordinated as an eta(3)-ligand. The sugar fragment occurs as
an envelope in the gauche-gauche conformation. The structure is suppo
rted by a network of hydrogen bonds.
