Two mixed-ligand polymeric complexes formulated as {[Zn（pda）（bpy）]·0.5H2O}n （pda = 1,4-phenylenediacetate, bpy = 2,2＇-bipyridine） 1 and {[Cd（pda）（bpy）]·1.5H2O}n 2 have been hydrothermally synthesized. Single-crystal X-ray diffraction analyses reveal that the structures of complexes 1 and 2 possess similar one-dimensional zigzag chains. Crystal data for compound 1： monoclinic, space group P21/c, a = 15.965（2）, b = 8.305（1）, c= 14.856（2） °A, β= 111.048（2）°, Mr = 422.73, V = 1838.2（4）°A^3, Z = 4, Dc = 1.528 g/cm^3, μ= 1.368 mm^-1, F（000） = 868, the final R = 0.0783 and wR = 0.1469 （w =1/[σ^2（Fo^2）＋（0.0351P）^2＋ 8.0014P], where P = （Fo^2 ＋ 2Fc^2）/3） based on 2025 observed reflections with I〉 2σ（I）; and those for compound 2： monoclinic, space group C2/c, a = 29.921 （7）, b = 8.5400（17）, c = 15.320（3） °A,β= 99.59（3）°, Mr = 487.75, V = 3859.9（14） °A^3, Z = 8, Dc = 1.668 g/cm^3, μ= 1.169 mm^-1, F（000） = 1936, the final R = 0.0723 and wR = 0.1612 （w = 1/[σ^2（Fo^2）＋（0.0681P）^2 ＋ 55.9577P], where P = （Fo^2 ＋ 2Fc^2）/3） based on 2130 observed reflections with I〉 2σ（I）. Fluorescent analyses show that both complexes exhibit intense blue luminescence （λmax = 485 nm for 1 and 475 nm for 2） upon excitation at 330 nm.

Orthorhombic-phase NaMgF3, composed of bio-friendly elements of Na, Mg and F, is considered to be an ideal host matrix for preparing trivalent lanthanide(Ln3+)-doped luminescent nanocrystals(NCs) with color-tunable emissions for diverse biological applications. However, the preparation and the survey on optical properties of ultrasmall(< 10 nm) Ln3+-doped NaMgF3 NCs remain nearly untouched to date. In this paper, we report a series of monodisperse Ln3+-doped orthorhombic-phase NaMgF3 NCs with an average size of ~10 nm that was synthesised by using a modified high-temperature co-precipitation method. Utilizing Eu3+ ion as an efficient optical/structural probe, the successful hetero-valence doping of Ln3+ ion into the lattice of NaMgF3 NCs is well-established irrespective of their different valences and radii between the host cation(e.g. Mg2+) and Ln3+ dopant. Benefiting from this, desirable upconversion luminescence(UCL) ranging from ultraviolet(UV) to visible and to near-infrared(NIR) spectral regions can be easily obtained after the doping of typical UCL couples of Yb3+/Er3+, Yb3+/Tm3+ and Yb3+/Ho3+ into the NaMgF3 NCs upon excitation by using a 980-nm diode laser.
