Step by step crystal-to-crystal transformation from 1D K2Cu(C2O4)2(H2O)4 (1) to 1D K2Cu(C2O4)2(H2O)2 (2) and then 1D K2Cu(C2O4)2 (3) by dehydration†
Abstract
A step by step crystal-to-crystal transformation was observed from the 1D tetrahydrate compound K2Cu(C2O4)2(H2O)4 (1) to the 1D dihydrate compound K2Cu(C2O4)2(H2O)2 (2), and finally the 1D dehydrated compound K2Cu(C2O4)2 (3) by the loss of half the amount of H2O and all H2O molecules, with structural and magnetic changes.
