Sodium pertechnetate is the inorganic compound with the formula NaTcO4. This colourless salt contains the pertechnetate anion, TcO
4
that has slightly distorted tetrahedron symmetry both at 296 K and at 100 K[2] while the coordination polyhedron of the sodium cation is different from typical for scheelite structure. The radioactive 99m
Tc
O
4
anion is an important radiopharmaceutical for diagnostic use. The advantages to 99m
Tc
include its short half-life of 6 hours and the low radiation exposure to the patient, which allow a patient to be injected with activities of more than 30 millicuries.[3] Na[99m
