Rubidium pertechnetate is a pertechnetate of rubidium, with the chemical formula RbTcO4.

Preparation

Rubidium pertechnetate can be prepared by reacting rubidium carbonate with ammonium pertechnetate:[2]

Rb2CO3 + 2 NH4TcO4 → 2 RbTcO4 + (NH4)2CO3

Properties

Rubidium pertechnetate crystallizes in the tetragonal crystal system, with space group I41/a, and lattice parameters a = 576.2 pm and c = 1354.3 pm. In its structure, the Tc–O bond length is 172.3 pm, O–Tc–O bond angle is 108.34°.[2]
