Complexation of Tolane by Fluorinated Organomercurials—Structures and Luminescence Properties of an Unusual Class of Supramolecular π-Coordination Polymers

Intermolecular interactions in polymorphs of the cyclic trimeric perfluoro-ortho-phenylene mercury from geometric, energetic and AIM viewpoints: DFT study and Hirshfeld surface analysis

“…Thus, the macrocycle 1 was found to be able to interact with both anions [9][10][11][12][13] and neutral electron-rich molecules (see reviews [4,8,14] and recent studies cited in Refs. [15][16][17][18][19][20][21][22][23][24]). Coordination ability of 1 was utilized for molecular recognition in catalysis and organic synthesis [25][26][27], as well as for various ion-sensitive material chemistry, supramolecular self-assembly and design of crystalline materials [8,14].…”

Coordination chemistry of mercury-containing anticrowns. Self-assembly of unusual supramolecular aggregates in the interaction of the three-mercury anticrown (o-C6F4Hg)3 with crown ethers in the presence of neutral monodentate oxygenous Lewis bases

“…Macrocyclic multidentate Lewis acids or anticrowns 1 represent a novel class of anion receptors and catalysts (see reviews references 2-8 and references cited in recent papers references [9][10][11][12][13][14][15][16][17].…”

“…Previously, we have reported the ability of one of the most studied anticrowns, viz., cyclic trimeric perfluoro-o-phenylenemercury (o-C 6 F 4 Hg) 3 1, having a plane structure, 18 to coordinate [12]crown-4, [18]crown-6 and the simplest representative of crown ethers -1,3,5-trioxane. 15 In the case of [12]crown-4 and [18]crown-6, the complexation reactions proved to be extremely sensitive to the presence of moisture in the system.…”

It turned out that when aqueous crown ethers are used in these experiments or when the reactions of the corresponding anhydrous crown ethers with 1 are carried out in contact with air moisture, the resulting complexes {[(o- 2 } 2 contain the coordinated water molecules along with the starting crown compound.…”

“…An additional contribution in the formation of 2 is made by the interaction of four oxygen atoms of the crown ether with the Hg centres of the anticrown molecules. The synthesis of an anhydrous adduct of 1 with [12]crown-4 has been accomplished by the reaction of 1 . EtOH 14 with the corresponding anhydrous crown ether in dry diethyl ether under Ar.…”
