kE in textbook

Postby Lauryn Shinno 2H » Sat Dec 01, 2018 5:11 pm

Hi in the 6th edition of the textbook, toolbox 17.1 says "If there is an ambiguity in which atom is linked to the metal atom, then kE is added to the name in parentheses, where E denotes the connecting atoms (and k is kappa):[Fe(NCS)(OH2)5]2+ thiocyanato(kN)pentaaqua(III) iron [Fe(NCS)(OH2)5]2+ thiocyanato(kS)pentaaqua(III) iron.
Do we have to know this? How do you know which one is the connecting atom?

I am not completely sure if we need to know this or not. But as for how do we know which is the connecting atom, the atom after the k is the atom that connects to the metal. In the first case N bonds with Fe from NCS while in the second one S bonds with Fe.
