17.29 a

Postby Wenxin Fan 1J » Wed Nov 29, 2017 1:11 am

Why is [Fe(CN)6]-4 hexacyanoferrate(II) instead of hexacyanidoferrate(II)? Shouldn't it be cyanido instead of cyano? are both correct? Table 17.4 says CN- is cyanido but can also be iso-cyano.

Please help!

Both are correct. The older naming system uses "cyano" and the newly revised IUPAC definitions use "cyanido". The term "iso-cyano" refers to a cyanide ligand attached at the N.
