![]() In that part, there are a number of things attached to the transition metal. The stuff inside the square brackets always makes up one of the ions. The formulae for coordination complexes always give you hints about the structures. This time, the anion is the more complex part, and there are two potassium ions as well. Potassium hexachloroplatinate, K 2, is another good example. ![]() There is a cationic part, which itself is a moderately complicated structure, plus three chloride anions. The "complex" part refers to the fact that the compound has a bunch of different pieces. Hexaamminecobalt(III) chloride, Cl 3, is an example of a coordination complex. These species bind to the metal ions, forming coordination complexes. These metal ions are not found by themselves, instead, they attract other ions or molecules to themselves. They are often brightly-colored compounds and they sometimes play very useful roles as catalysts or even as pharmaceuticals.īecause of their relatively low electronegativity, transition metals are frequently found as positively-charged ions, or cations. These compounds are called transition metal complexes or coordination complexes. Many of these compounds are ionic or network solids, but there are also some molecular compounds, in which different atoms are arranged around a metal ion. In addition to being found in the metallic state, they also form a range of compounds with different properties. ![]() Transition metals are found in the middle of the periodic table. ![]()
