Three-dimensional silver(I) co-ordination polymer with pocket structures

Abstract

Silver() complexes of hexakis(phenylsulfanyl)benzene (hphb), [Ag 2 (hphb)][PF 6 ] 2 1 and [Ag(hphb)(NO 3 )] 2, have been prepared and their molecular structures determined by X-ray crystallography. In 1 the silver ion adopts a tetrahedral co-ordination geometry comprising four S atoms from two different hphb molecules and giving an eight-membered Ag-S ring structure in a co-ordination polymer. This ring (6.46 × 6.79 Å) forms a three-dimensional framework with pockets. On the other hand, for 2, the silver() ion has a square pyramidal environment with four S atoms and one O atom of a NO 3 Ϫ anion. The complex forms a linear-chain structure with an alternating arrangement of silver ions and hphb.

“…In another study, hexakis(phenylthio)benzene was self‐assembled in the presence of Ag I salts to produce either a three‐dimensional network coordination polymer with pocket structures or linear chains, depending on the counterion used 98. In the presence of PF 6 − , a coordination polymer with pockets was obtained (Figure 19), whereas NO 3 − generated a linear coordination polymer (Figure 20).…”

Synthesis of fluorinated trithioether compounds

“…'s constrained to 1 for each pair of disordered atoms, converging to 0.813(9)/0.187(9) for F12/F16, 0.780(11)/0.220 (11) for F19/F23, and 0.464(12)/ 0.536(12) for F26/F30. Three bond lengths were restrained in order to reach a sensible geometry for C-F groups corresponding to minor disordered components: C16-F16 = 1.345 (20), C23-F23 = 1.345 (20), and C26-F26 = 1.345(20) Å . Pertinent crystal data are collected in Table 1 and complete crystallographic information has been deposited with the CCDC (deposition numbers: 276906, 276907, and 276908 for 1, 2, and 3, respectively).…”

“…In this field, tripodal ligands with arene cores have been designed for construction of cagelike architectures [12][13][14][15], and polythiolate and polythioether ligands possess an unusual potential for structure control in crystal construction. So, interesting crystal structures of transition metal complexes with tripodal trithiolate [16,17] and polythioether [18][19][20][21][22] ligands have been reported, and some examples of organic polythioether ligands have been structurally characterized [21,[23][24][25][26].…”

Distinct host–guest interaction and subdued fluorescence in a coordination network of 2,3,6,7,10,11-hexakis(phenylthio)triphenylene and silver(I) triflate

“…Among the numerous related molecules subsequently reported [3][4][5][6][7], highly branched star-shaped molecules have also attracted attentions because of potentially important properties such as electroactivity [8,9], intermolecular recognition [10] and fluorescent sensing [11]. Notably, star-shaped molecules have also entered into the field of crystalline networks for accessing porous or pocket-containing structures, where a wide range of diffusion or host-guest interaction phenomena could potentially be investigated in the context of extended networks [12][13][14][15][16][17][18][19][20].…”
