If not all unsaturated atoms of a l igand are involved in bonding, if a l igand can adopt several
bonding modes, or if a l igand bridges several metal atoms, the locants of the ligating atoms
appear i n a numerical sequence before the symbol Z, w hich is preceded by a h yphen.
Extended coordination over more than two contiguous carbon atoms should b e i ndicated by,
for example, (1–4-Z) r ather than by (1,2,3,4-Z). The l ocants and the symbol Z are enclosed
in parentheses. No superscript on the symbol Z is then necessary.
