In Situ Hydrothermal Synthesis, Crystal Structure, and Properties of a New Inorganic Holmium–Sulfate Coordination Polymer

A new chiral holmium–sulfate coordination polymer, {Ho4(OH)4(SO4)4(H2O)3}n (1), has been synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction. The X-ray diffraction analysis reveals that 1 crystallizes in orthorhombic space group P212121 and exhibits a unique three-dimensional chiral structure, in which {Ho4} building blocks are linked by SO42– anions to form a high connected binodal network. Furthermore, thermal and luminescence properties of 1 are investigated in the solid state.
