“…To our knowledge, this dual role of Hbpy has not been observed in porous solids before. Normally, a similar amount of torsion is observed between the two pyridyl rings for neutral bpy molecules, as either template or ligand, with dihedral angles around 25° (Supporting Information, Figure S5) 11c. However, in NTHU‐8, the degree of torsion is found to be much different in the ligand Hbpy and template Hbpy, with the dihedral angles being 10.0° and 19.2°, respectively.…”

In the last decade, the synthesis of nanoporous materials with extended network topologies has advanced extensively owing to the increasing demand for functional materials in applications involving molecular recognition, shape-selective catalysis, fluid separation, and hydrogen gas storage.[1] Until now, two major categories of nanoporous structures have been under intense investigation: one with whole inorganic framework, such as silica-based zeolites, germanates, and phosphorous-based metal oxides; and another with organic-inorganic hybrid frameworks; that is, porous coordination polymers [2] and metal-organic frameworks (MOFs).[3] The largest pore and/or channel opening that has been observed in inorganic frameworks are 18-membered rings (18MR) in silicates, [4] 24MR in metal phosphates, [5] 26MR in metal phosphites, [6] and 30MR in germanates. [7] In the hybrid frameworks, however, the cavities were determined from pore structure analysis based upon gas sorption studies. By using bulky organic units to co-construct the framework, even higher porosity or larger pores can be produced. For example, the pore size found in the framework MIL-101 [8] was up to 4.6 nm, and the void space in MOF-177 [9] was reported to increase the size of a unit-cell volume by up to 81 %, thus substantially surpassing the volume of inorganic structures.Exploration of enhanced porosity and even new properties in the inorganic framework have thus been pursued by mediating with organic building units. To date, transforming inorganic frameworks into hybrid frameworks has only been possible in phosphate/phosphite (MPO) systems; few organic molecules are found to be suitable, for example, the smallest oxalate linker and certain polyamine molecules. Encouragingly however, quite a few unique three-dimensional metal oxalatophosphates [10] and pillar-layered organo-metallophosphates (OMPO) [11] have been formed that have extra-large channels with interesting properties. The oxalate-mediated nanoporous gallium phosphates of NTHU-6[10a] or NTHU-7, [10b] with their unprecedented photoluminescence properties, has established a new class of LED color-conversion phosphors. Aryl carboxylates, such as benzene dicarboxylate (bdc) or benzene-1,2,4,5-tetracarboxylate (btec), which are effective organic building units of MOFs or coordination polymers, had not been found to adapt to MPOs until the discovery of (H 2 tmdp)[(ZnHPO 4 ) 2 (bdc)] (tmdp = 4,4'-trimethylenedipyridine; NTHU-2),[11a] the first bdc-mediated OMPO compound, in 2004. This compound has gismondinelike inorganic sheets pillared by bdc to give nanometer-sized channels and a remarkable gas sorption behavior; of vital importance, this sorption revealed bimodal pore-size distributions. To gain a deeper insight into the intriguing and useful porous properties, we have focused on the study of carboxylate-incorporated MPO frameworks. Herein we report the first btec-mediated metal phosphate compound, (Hbpy)-[Zn 2 PO 4 (btec)(Hbpy) 2 ] (bpy = 4,4'-bipyridine), designated NTHU-8. This compound e...

“…Templating Hbpy ions fill in the channels and balance the charge. Usually, bpy molecules tend to remain neutral as bridging linkers 11b,c. Protonated forms of bpy, especially the monoprotonated, are relatively seldom in phosphate‐containing structures.…”

“…Almost all uranium(VI) in crystal structure is present as an approximately liner UO 2þ 2 uranyl cation [6], which is an attractive metal center from which one may construct polymeric and framework materials [7]. Due to its considerable compositional range, chemical and structural diversity with various dimensionalities, properties and potential applications in nuclear industry, ion-exchange and catalysis [8][9][10][11][12][13][14][15][16][17], the compounds containing uranyl ion attract considerable attention.In order to gain a better understanding the bonding of coordination polymer of the uranyl cation and organic ligand, an organic acid named tris(2-carboxyethyl)isocyanurate (tciH 3 ) has been chosen as a model compound to react with UO 2þ 2 . While tciH 3 has been previously employed to create polymeric materials [18], there are no reports of any uranium-tciH 3 compounds to date.…”

“…Among them, compounds based on 4,4-bipyridine (Bipy) ligand have shown special charm due to their various aesthetic structures as well as abundant potential applications. As a rigid, rod-like organic building block, Bipy may act as a ligand connecting two metal ions or a linker bridging two metal complex moieties [4,5], a pillar bonding to an inorganic skeletal backbone [6], a charge compensating cation [7], or an isolated guest molecule and organic template [8], to construct various structures, including zero-, one-, two-, and threedimensional motifs exhibiting zigzag chain, ladder, grid, brick, railroad, diamondoid, and octahedral building blocks. On the other hand, the Bipy ligand possesses a delocalized π-electron system, which makes it an excellent candidate for preparing luminescent compounds with abundant potential applications, such as emitting materials in diodes [9], sensitizers in solar energy conversion [10], and chemical sensors [11].…”

The solvothermal reaction of 4,4′-bipyridine (Bipy) and mercury nitrate in a mixed acetonitrile/water solution leads to a novel mercury coordination compound with the in situ formation of cyanide ions Hg(Bipy)(CN) 2 (1). Its structure is determined by single crystal X-ray diffraction (XRD), and further characterized by powder XRD, elemental analysis, and IR spectroscopy. Compound 1 exhibits a 1D zigzag [Hg(Bipy)(CN) 2 ] n chain structure. The solid-state photoluminescent properties of 1 are also investigated.
