摘要：

Two cobalt hexammine-vanadate ion-pair complexes have been prepared; one in acid medium (pHapproximate to4) and the other in alkaline medium (pHapproximate to10). The formed complexes were characterized by their elemental analysis, IR and XRD techniques. The complexes were subjected to thermogravimetric and differential thermal analyses. The IR study suggests that the formed complexes were of the ion-pair type, while that of the thermally decomposed compounds revealed the resolution of the originally present broad V=O and V-O-V bands.
