Thallium orthovanadate

Thallium Orthovanadate, T13V04, is a light brown substance obtained by carefully fusing three molecular proportions of thallium carbonate... 

Thallium Pyrovanadate, T14V20 is precipitated as a light yellow powder by the addition of thallium sulphate to a cold, saturated solution of sodium orthovanadate. It also results on fusing a mixture of vanadium pentoxide and thallium carbonate.14 It melts at 454°15 or 416° C.,16 and is soluble in about 5000 parts of water at 14° C. 

Thallium(in) orthovanadate has been prepared by the reaction of TI2O3 V2O5 in the presence of H2O. This species has never before been reported, and it was characterized by its chemical reactions and its thermal behaviour, decomposing above 300 °C, thus ...
