According to recent research from Shenyang, People's Republic of China, "Single crystals of KTb(C2O4)(SO4)(H2O), potassium aquaterbium(III) oxalate sulfate, were obtained under hydrothermal conditions. In the crystal structure, the Tb(III) atom is coordinated by four O atoms from two oxalate anions, three O atoms from three sulfate anions and one O atom from a water molecule within a TbO8 distorted square antiprismatic coordination."
"The potassium and terbium(III) atoms are bridged by the oxalate and sulfate groups, forming a three-dimensional structure. The coordination mode of the oxalate has not yet been reported," wrote Y.G. Sun and colleagues.
