Mechanochemical conversion of nano potassium hydrogen terephthalate to thallium analogue nanoblocks with strong hydrogen bonding and straight chain metalophillic interactions

Abstract

6 -HTA)] n (1), [H 2 TA = terephetalic acid], prepared by sonochemical procedure, to Tl I analogue coordination polymer nanoblocks was studied. The structure of [Tl(μ 3 -HTA)] n (2) is exactly the same as 1 and the Tl ion has distorted octahedral coordination. The carbonyl oxygen is coordinated to two different metal ions, while another oxygen atom is bonded to one metal and participates in a very strong hydrogen bond. Both compounds have secondary straight chain metallophilic interactions. In addition to the same structures of 1 and 2, the same crystal data of them also approved that the chemistry of thallium(I) parallels that of the potassium(I) in many ways.

Sonochemical synthesis of a two‐dimensional supramolecular polymer with nanoporous morphology, linear thallophilic and covalent hydrogen‐bonding interactions

“…This type of Tl...Tl and covalent hydrogen bonds are scarce in the literature. Surprisingly, the structure of 1 is very similar to [Tl( μ 3 ‐HTA)] n ( 2 ), (H 2 TA = terephetalic acid), which was reported previously …”

“…Herein, we wish to report a new thallium‐based coordination polymer, [Tl( μ 3 –3‐HClb)( μ 3 –3‐Clb)] n ( 1 ) with linear thallophilic and covalent hydrogen‐bonding interactions, which was characterized by IR spectroscopy and single‐crystal X‐ray diffraction. Prior to this study, some coordination polymers with metallophilic interaction, such as [Na( μ 2 ‐Hdcpa)( μ 3 ‐dcpa)] n , (Hdcpa = 2,4‐dichlorophenoxyacetic acid), [Tl( μ 3 ‐HTA)] n , (H 2 TA = terephetalic acid) and {[Ag(1‐methylhydantoin)]·0.5H 2 O} n , were reported. Moreover, the effects of ultrasonic irradiation, the concentration of initial reagents and types of solvents on the formation of the nanostructure of compound 1 were investigated.…”

Solid–Liquid Conversion and Carbon Dioxide Storage in a Calcium-Based Metal–Organic Framework with Micro- and Nanoporous Channels

“…However, unfortunately, the crystallization process of this compound in water was not successful. In an continuation of our previous work on investigating the structural conversion of MOFs , and coordination polymers, − in this case a comparison between the PXRD pattern of the A phase with those of other reported MOFs constructed from Ca 2+ and terephthalic acid in the presence of water was done in order to find some similar patterns (Figure S8 in the Supporting Information). (1) A PXRD pattern (Figure S8 in the Supporting Information) that is attributed to a MOF with the formula [Ca­(BDC)­(DMF)­(H 2 O)] n formula was similar to that of the A phase.…”

A new potassium‐based coordination polymer with hydrogen bonding and zigzag metallophilic interactions

“…Herein, we wish to report a potassium‐based coordination polymer, [K ( μ 7 ‐HTar)] n ( 1 ) with zigzag chain K···K metallophilic interactions, which was characterized by IR spectroscopy and single‐crystal X‐ray diffraction. Prior to this study, some coordination polymers with metalophilic interaction such as [Na (μ 2 ‐Hdcpa)(μ 3 ‐dcpa)] n , (Hdcpa = 2,4‐dichlorophenoxyacetic acid), [Tl (μ 3 ‐HTA)] n , (H 2 TA = terephetalic acid) and {[Ag(1‐methylhydantoin)]·0.5H 2 O} n were reported. Moreover, the effects of ultrasonic irradiation, concentration of initial reagents and types of solvents on formation of compound 1 nanostructures were investigated.…”
