The synthesis, structure, and magnetic studies of one supramolecular PtS net

Abstract

A new 2-D coordination polymer, Co(H₂O)₂(Hoba)₂ (1) [H₂oba = 4,4′-oxybis(benzoic acid)], was synthesized under hydrothermal conditions. Polymer 1 has been characterized by single-crystal X-ray diffraction and TG analysis. Through hydrogen bonds 1 shows a supramolecular four-connecting 3-D matrix with 4²8⁴ PtS topology. Magnetic studies reveal antiferromagnetic interactions.
