Are there compounds more conductive than Silver (Ag)? Silver is the most electrically conductive element on the Periodic Table. However, I am interested in knowing if there are any compounds (combinations of elements) that would be more conductive than Silver (without Superconductor cooling). The extreme electrical conductivity of specific chemicals has many real world applications, from simply calling someone miles away, to processing enormous amounts of data in servers.
Graphene supposedly has higher conductance.

The [...] resistivity of graphene sheets would be 10−6 Ω⋅cm. This is less than the resistivity of silver, the lowest otherwise known at room temperature.

but it is not a compound - it is a homonuclear molecule.
