Abstract

Cobalt oxalate has two hydrated forms: tetrahydrate CoC2O4• 4H2O and dihydrate CoC2 O4• 2H2O, which dehydrate at about 280 K and 420 K, respectively (1). Cobalt oxalate dihydrate crystallizes during prepicitation as an orthorombic ß-phase. However, it recrystallizes in the solution and forms thermodynamically stable monoclinic a-phase (2). Morphology in the crystals is to a great extent due to this transformation.
