“…Note that complex 2 is 15 nm red‐shifted compared to 1 . This is probably due to the different nature and coordination environments of the central Zn II or Cd II ions and the different structures of complexes 1 and 2 27. Unfortunately, the luminescent lifetimes of complexes 1 and 2 are not observed, since they are too short to be measured.…”

Abstract. Two coordination polymers, namely, [Zn(bpe)0.5(Htbip)(tbip)0.5]·H2O (1) and [Cd(bpe)0.5(tbip)] (2) [H2tbip = 5‐tert‐butylisophthalic acid and bpe = 1, 2‐ bis(4‐pyridyl) ethane] were synthesized through hydrothermal reactions. Single‐crystal X‐ray diffraction analysis reveals that complex 1 presents a three‐dimensional (3D) six‐connected uninodal structure with the type of topology of svi‐x/I4/mcm → Ibam, whereas complex 2 holds a 2D 44‐sql layer structure. Moreover, the photoluminescent properties of the complexes at room temperature were investigated.

“…Given the advances in carboxyphosphonate chemistry, we decided to open up the field of aromatic aminocarboxyphosphonates by incorporation of an amino group into the benzene scaffold, since the effect of that group on coordination preferences and properties has been scarcely recognized to date. , The structure of a ligand designed for this purpose, 3-amino-5-(dihydroxyphosphoryl)benzoic acid ( H 3 APB ), is presented in Scheme . By reaction with copper(II) salt, we obtained a three-dimensional CP, 1 , featuring structural flexibility, which has been proved by hydration–dehydration experiments; moreover, the presence of “diamond chains” of copper(II) ions allowed us to characterize its spin-frustrated magnetic properties.…”

While metal−organic frameworks (MOFs) or, more generally, coordination polymers (CPs) built using linkers possessing two different functional groups are known very well in the literature, the effect of a third functional group on the physicochemical properties of those materials is weakly recognized. To study this issue we designed an aminocarboxyphosphonic ligand, 3-amino-5-(dihydroxyphosphoryl)benzoic acid (H 3 APB), which is an amino derivative of metaphosphonobenzoic acid. By self-assembly with a copper(II) source, we obtained the three-dimensional CP {[Cu 3 (APB) 2 -(H 2 O) 6 ]•6H 2 O} n , 1, featuring rare binodal 4,5-connected tcs topology. By comparison with previously known representatives of that topology, we put forward a hypothesis that CPs of rare topologies, such as tcs, are obtained when polytopic, differentially substituted ligands are used. The structure of 1 is layered, but not in the manner typical for "traditional" metal phosphonates and carboxyphosphonates, and it was found to be flexible; structural flexibility has been demonstrated by dehydration−hydration experiments. The structural changes were probed with the use of PXRD and IR methods. We have also shown that the copper(II) aminocarboxyphosphonate 1 presented herein has moderate capability for degradation of methylene blue, rhodamine B, and acridine orange in oxidizing conditions; however, the rate of dye degradation is greatly enhanced under visible light irradiation. Analysis of magnetic properties revealed that 1 is a spin-frustrated system with a diamond-chain arrangement of copper(II) ions. The magnetic data were fitted using the isotropic Heisenberg as well as Ising models. Both models consistently indicate that magnetic exchange paths are both antiferromagnetic and ferromagnetic, with dominating participation of the former interaction.

“…Metal phosphonates are of great research interest because of their structural and compositional diversity, as well as their thermal and chemical stability for potential applications as porous materials, ion exchangers, proton conductors, Langmuir–Blodgett films, nonlinear optics, molecular sensors, catalysts, magnets, etc. − Because of the low solubility and crystallinity of metal phosphonates, it is still difficult to grow single crystals of a suitable size and high quality for X-ray structural analysis. In recent years, much effort has been devoted to modifying phosphonic acids with additional groups, including amino, carboxylate, pyridyl, triazole, thienyl, and imidazole groups. − This is due to the fact that additional groups can enrich coordination modes to improve the solubility and crystallinity of metal phosphonates. As a result, a variety of intriguing metal phosphonates have been obtained and structurally characterized, such as calcium phosphonates with tuned proton conductivity .…”

Hydrothermal reactions of Zn(CH 3 COO) 2 •2H 2 O with two new triazine-based phosphonic acids, 2,4,6-triglyphosate-1,3,5-triazine (H 9 L1) and 4,6biglyphosate-2-hydroxyl-1,3,5-triazine (H 6 L2), afforded two new zinc phosphonates, namely, [(C 5 H 14 N 2 )Zn 3 (HL1)(H 2 O)]•3.5H 2 O (1) and [(C 5 H 14 N 2 )-Zn 2 L2]•3H 2 O ( 2), respectively. The two zinc phosphonates were structurally characterized through single-crystal X-ray diffraction. Compound 1 is a threedimensional (3D) framework in that Zn−O−P chains are connected by HL1 8− anions with hendecadentate modes. In compound 2, each L2 6− anion links four Zn2 binuclear units to form a 3D framework. In both compounds 1 and 2, the protonated 2-methylpiperazines are encapsulated into the channels of 3D frameworks. Thermogravimetric analysis and powder X-ray diffraction reveal that compounds 1 and 2 are thermally stable up to 200 and 160 °C under an air atmosphere, respectively. Compounds 1 and 2 display near-UV and purple luminescence with maximal bands at 377 and 402 nm, respectively. It worth noting that the luminescence of solids 1 and 2 can be preserved after compounds 1 and 2 are heated at 200 and 160 °C for 2 h under an air atmosphere, respectively. In addition, the ion-exchange property of compound 1 was also studied.
