... This time the possible cross-products are K with SO4 and Ag with PO4. Let’s check whether either of these meets one of the three criteria: K-SO4 is not insoluble (by rule #1); it is not a weak acid (no H); and it is not a decomposer. So we know K and SO4 are out of the running. We can see by rule #4 ...

Coordination complex
In chemistry, a coordination complex or metal complex consists of a central atom or ion, which is usually metallic and is called the coordination centre, and a surrounding array of bound molecules or ions, that are in turn known as ligands or complexing agents. Many metal-containing compounds, especially those of transition metals, are coordination complexes.
