Coordination chemistry of mercury-containing anticrowns. Synthesis and structure of an unusual discrete, double-decker sandwich complex of cyclic trimeric perfluoro-o-phenylenemercury with an aromatic hydrocarbon

Coordination Chemistry of Mercury-Containing Anticrowns. Complexation of Perfluoro-o,o′-biphenylenemercury with o-Xylene and Acetonitrile and the First X-ray Diffraction Evidence for Its Trimeric Structure

“…4,5,16,17 The majority of these 1:1 complexes form in the crystal extended binary stacks representing polydecker sandwiches wherein the arene molecules alternate with the molecules of 1. 4,5,16 However, on using [2.2]paracyclophane, a discrete, double-decker sandwich complex was obtained in the interaction with 1.…”

“…4,5,16 However, on using [2.2]paracyclophane, a discrete, double-decker sandwich complex was obtained in the interaction with 1. 17 In the case of the complexes of 1 with benzene, o-xylene, and some other arenes, all three Hg atoms of (2) 3.518 (1) 3.535 (1) 3.651 (1) 3.742(1) Hg(1)···Hg (3) 3.559 (1) 3.407 (1) 3.479 (1) 3.607(1) Hg (2) A different mode of bonding is realized in the interaction of perfluorinated three-mercury anticrown 8 with o-xylene and acetonitrile. Here, as mentioned above, each molecule of the Lewis basic guest in the resulting complex is coordinated by only one Hg center of the corresponding anticrown molecule.…”

Coordination Chemistry of Anticrowns. Synthesis and Structures of Complexes of the Perfluorinated Three‐Mercury Anticrown (o‐C6F4Hg)3 with Monohalogenobenzenes

“…In the last decades, there has been considerable interest in the binding and catalytic properties of macrocyclic multidentate Lewis acids representing antipodes of conventional crown compounds and called anticrowns (see reviews and papers cited in refs). These remarkable reagents exhibit a high affinity toward various anions and neutral Lewis bases forming complexes with them wherein the Lewis basic species is cooperatively coordinated by all Lewis acidic centers of the anticrown.…”

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].…”
