Synthesis, Crystal Structures, and Properties of Three Complexes of 5-(pyridin-2-ylmethoxy) Isophthalic Acid

Abstract

Three new coordination compounds, namely, [(HL)₂M(H₂O)₄] (M = Co, (1); M = Mn, (2); M = Ni, (3), H₂L = 5-(pyridin-2-ylmethoxy) isophthalic acid), have been hydrothermally synthesized and characterized by elemental analysis, IR, and single-crystal X-ray diffraction. The structures of complexes 1–3 are strikingly similar and the three complexes are mononuclear compounds. In complexes 1–3, the H₂L ligand is partially deprotonated. In addition, the photoluminescent behavior of 2 and the H₂L ligand has been investigated in detail.
