Solvothermal Synthesis, Crystal Structure, and Properties of a New Organic‐Templated Holmium Sulfate with 1D Single Ladder Chains

A new organic amine templated 1D holmium sulfate (C2H8N)[Ho(SO4)2·H2O] (1) has been synthesized and solvothermally and structurally characterized by single-crystal X-ray diffraction, IR spectroscopy, thermogravimetric and X-ray diffraction analyses as well as scanning electron microscopy (SEM). The structure of framework 1 is constructed from HoO8 polyhedra and SO4 tetrahedra. S(1) and S(2) connects Ho(1) and its crystallographic partners by using three S–O–Ho linkages to generate double chains, whereas the adjacent double chain are connected by μ3-O (O5) atoms to form a novel single ladder chains.
