“…For instance, Huang and his coworkers have employed a V‐shaped dipolar ligand to react with d 10 Cd(II) salt, producing an noncentrosymmetric 1D metallacyclic chain. Interestingly, such 1D metallacyclic chains adopt different arrangement modes, resulting in the formation of one noncentrosymmetric and one centrosymmetric structures [10] . Based on above analysis, we designed and synthesized a new asymmetric rigid bridging ligand 3,5‐dimethyl‐ N ‐(pyridin‐4‐ylmethylene)‐4 H ‐1,2,4‐triazole‐4‐amine (PTA, Scheme 1).…”

Two noncentrosymmetric d10 metal centered coordination polymers with formula [Zn(PTA)Cl2] ⋅ H2O (1) and [Hg3(PTA)3Cl6] (2) have been successfully prepared by the reaction of rigid non‐centrosymmetric ligand 3,5‐dimethyl‐N‐(pyridin‐4‐ylmethylene)‐4H‐1,2,4‐triazole‐4‐amine (PTA) and corresponding metal salts ZnCl2 and HgCl2. Both 1 and 2 feature acentric 1D zigzag chain arrangements, in which each chain is composed of linear 2‐connected PTA ligands and V‐shaped 2‐connected metal nodes Zn(II) or Hg(II). Complex 1 possesses C2 symmetric eqitlateral 1D zigzag chain structure and corresponding crisscross array. In contrast with 1, 2 displays dissymmetric ineqitlateral 1D zigzag chain structure and common parallel arrangement. Being their acentric essence as well as colorless and transparent merits, the preliminary powder NLO properties of 1 and 2 were invesigated in solid‐state. The results indicated that the SHG intensities of 1 and 2 are about 1 and o.5 times that of commercial KDP.

“…Much effort has been devoted to the construction of entangled polymers through introduction of N-containing auxiliary ligands. − Inspired by this consideration, our synthetic strategy is reasonable selection of N-donor ligand to acquire entangled MOFs with H 3 bcpt ligand. The rod-like N-donor building blocks, 4,4′-bipyridine, have been extensively employed in coordination chemistry. − Furthermore, the modified 4,4′-bipyridine derivatives bpa and bpp, which have different spacers between the two 4-pyridyl groups, can cause a distinct spatial effect, thus resulting in unexpected entangled architectures. − Meanwhile, to explore the conformation of N-donor ligands on the entangled motif, three types of bimidazole (biimpy, bib, bix) ligands with different conformations were chosen for the M-bcpt system.…”

A 2D network of {[Zn(Hbcpt)(H 2 O) 3 ]•7H 2 O} (1) was hydrothermally synthesized and structurally characterized. By employing different N-donor ligands into the system of 3,5-bis(4′-carboxyl-phenyl)-1,2,4-triazole (H 3 bcpt) and Zn(II) cations, six novel entangled coordination polymers, namely, {[Zn 2 (bcptbenzene, py = pyridine), were obtained. Singlecrystal X-ray diffraction analysis reveals that, with the different N-donor ligands, the resulting compounds present entangled structures with different topologies. Compound 1 shows a 2D (4, 4) network, and the adjacent sheets are extended into a 3D supramolecular framework via hydrogen-bonding interactions. Interesting, by introducing a series of ditopic N-donor ligands into the reaction system, compounds 2−7 with entangled structures were harvested. Compound 2 exhibits a 3D self-penetrating network with an 8-connected bcu topology. Compound 3 features an 8-fold dia network showing an unusual [4 + 4] mode of interpenetration. Compound 4 is comprised of two parts of undulated 2D 4 4 -sql networks, and the adjacent undulated layers are parallel interpenetrated to each other to give a 2D → 3D polycatenated framework. Compound 5 presents an unusual 3D self-penetrating network with a novel 4,6,6-connected trinodal network with the point symbol of ( 3Compound 6 shows a 2-fold interpenetrating 3D architecture with 6-connected sxd topology. Compound 7 displays an unprecedented self-penetration derived from abnormal [3 + 2] 5-fold interpenetrating dia subnets. Structural diversity of these compounds suggests that different N-donor ligands can induce the organic ligand to present different conformations and coordination modes, and the influence on the final structures. Furthermore, the luminescent properties of compounds 1−7 have been investigated in the solid state.
