Question

Quizplus · Accepted Answer

The complex contains a cobalt(II) ion, which is coordinated to three chloride ligands and one water ligand. The name for this complex ion is aquatrichlorocobaltate(II). The sulfur-containing ligands are named as thiocyanate ligands, denoted by the prefix "thio" and "cyanate" suffix. The bracketed portion of the formula shows a complex ion with a sulfur-containing ligand bonded to the cobalt ion, followed by a hydrogensulfido ligand, which is bonded to a sulfur atom in a thiocyanate ligand. The overall charge of the complex ion is -1.
