Background: 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 do hydrides that are bridging ligands link up?
Answer:<extra_id_0>.
<extra_id_0> link two metal centers<extra_id_1>
