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.
