Caesium pertechnetate is the pertechnetate salt of caesium, with the chemical formula of CsTcO4.
__TOC__
Preparation
Caesium pertechnetate can be prepared by reacting caesium carbonate and ammonium pertechnetate:
{{chem2|Cs2CO3 + 2 NH4TcO4 -> 2 CsTcO4 + (NH4)2CO3}}
Properties
Cesium pertechnetate is orthorhombic with space group Pnma (No. 62), and lattice parameters a = 572.6 pm, b = 592.2 pm and c = 1436 pm. The Tc–O-bond length in pertechnetate is 164.0 pm, and the O–Tc–O bond angle is 112.9°.{{cite journal|author1=Jamie Weaver|author2= Chuck Z. Soderquist|author3= Nancy M. Washton|author4= Andrew S.
