A 3D Coordination Polymer of Sm(III) Using Inorganic Sulphate and Organic Succinate Building Blocks

A lanthanide coordination polymeric network, [Sm2(suc)2(SO4)(H2O)2]n (1) (suc = succinate dianion), incorporating both organic succinate and inorganic sulphate building blocks, has been synthesized and characterized by single crystal X-ray diffraction analysis. The complex displays a 3D architecture with two crystallographic independent samarium(III) ions having a distorted capped square antiprismastic geometry with O9 donor set realized by six oxygen atoms from succinate, two from symmetry related sulphate anions and one from an aqua ligand
