Question

The number of binding sites in these chemical species defines their denticity. For 10 points each:
[10e] Name these chemical species that bind to metal ions to form coordination complexes.
ANSWER: ligands
[10m] These kinds of ligands, which are often denoted by the Greek letter mu, can connect to two or more metal ions. Ligands of this kind convert into terminal ligands and vice versa during namesake exchanges.
ANSWER: bridging ligands [accept bridge-terminal exchanges]
[10h] Two pentamminerutheium (“pen-tah-MEE-neh-ROO-thin-ee-um”) are bridged by a pyrazine ligand to form this doubly eponymous complex, whose two ruthenium ions display an apparent oxidation state of plus two and a half.
