Quizplus · Accepted Answer

The central metal ion is Co and is tetrahedrally coordinated by three chloride ions and one water molecule (hence aqua-). The overall charge is -1, indicating the presence of a negative counterion, which in this case is a sulfonate ion (₃(H₂O)) with a phosphate group (^-) bonded to it. The complex is therefore called aquatrichlorocobaltate(II).
