| Abstract: | Three two‐dimensional (2D) coordination complexes, namely Ca2(HL)2(H2O)5]n · 2nH2O ( 1 ), Sr(HL)(H2O)3]n · nH2O ( 2 ), and Ba(HL)(H2O)3]n · nH2O ( 3 ) H3L = 3‐(3‐carboxy‐phenoxy) phthalic acid], were synthesized by using the ligand H3L and alkaline earth metals. Structural analysis reveals that the structures of complexes 1 – 3 can be described as 2D networks with the point (Schälfli) symbol for net: {312 · 414 · 52} topology. Additionally, the thermal stability and solid‐state luminescent properties of compounds 1 – 3 were investigated at room temperature. The quantum yield (QY) of compound 2 is 10.75 %, which is much higher than the QY of the free H3L ligand (QYH3L < 1 %). |
