Context: In inorganic chemistry, hydrides can also serve as bridging ligands that link two metal centers in a coordination complex. This function is particularly common in group 13 elements, especially in boranes (boron hydrides) and aluminium complexes, as well as in clustered carboranes.

Question: What chemistry do hydrides serve as bridging ligands?
Answer: inorganic chemistry

Question: What do hydrides that are bridging ligands link up?
Answer: link two metal centers

Question: What group is briging ligands most common in?
Answer: group 13
