Solvothermal Synthesis of a Layered Open-Framework Cholorocadmium Oxalate, Cd_2(C_2O_4)_0.5Cl_3NaCl centre dot 4H_2O

摘要

The metathesis reaction between CdCl_2 centre dot 2H_2O and sodium oxalate in n-hexanol under solvothermal conditions yidlds a hybrid compound of formula Cd_2(C_2O_4)_0.5Cl_3NaCl centre dot 4H_2O. It consists of one-dimensional chains formed by Cd and Cl atoms, containing mu_2(Cl) and mu_3(Cl) bridges, and cross-linked by oxalate units to give a layered structure. The Na~+ ions and water molecules occupy the interlamellar spaces.
