Abstract

original image

More than meets the eye: The trigonal-planar complex [Co(CN)3]6− (see structure, Co red, C gray, N green; alkaline-earth-metal counterions are yellow) has some surprises in store. The CN ligand displays variation in bond length and charge, and Co follows a closed-shell (d10) concept.
