Two series of coordinated compounds [Ln₂(TZI)₂(H₂O)₁₀]_n·4H₂O (Ln = Er (1), Yb (2), Dy(3), (H₃TZI = 5-(1H-tetrazol-5-yl)isophthalic acid) and [Ln(TZI)(H₂O)₄]_n·3H₂O (Ln = Ho (4), Eu(5) and Sm (6)) were hydrothermally synthesized by different reaction conditions. Compounds 1–3 are isostructural and show a dinuclear motif, which further develop into a 3D H-bonding supra-molecular structure, and compounds 4–6 are also isostructural and have a 1D ladder-typed chain, which further interlinked into a 3D supra-molecular architecture by H-bonding interactions. Furthermore, the fluorescent properties of compounds 3–6 exhibit intense emissions corresponding to blue-violet (3 and 4), red (5) and orange red (6), respectively. By way of the careful regulation of the relative intensity of the blue-violet (4), green (Tb) and orange red (6) emissions, a novel three-component white-light emission (Ho–Sm–Tb) has been realized.
