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

Abstract

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 SO₄^2– anions to form a high connected binodal network. Furthermore, thermal and luminescence properties of 1 are investigated in the solid state.
