(Top) Optical micrographs of Sm2(C2O4)3·10H2O during dehydration to Sm2(C2O4)3·6H2O on heating. (Bottom) The orientation of the fragments of the crystal structures corresponds to the crystal shape. The hexahydrate crystal remains in the same plane. The product structure was calculated from optical microscopy observations and confirmed independently by single-crystal X-ray diffraction (see text). |
