Structure of the 2,5,8-trithia[9](2,6)pyridinophane–silver nitrate complex (1:1)

Synthesis and Binding Properties of 1,3,5-Tris(2-arylthiomethyl)mesitylene: A Selective Ag (I) Ionophore

“…The NMR results also corroborate with this interpretation. On the other hand, semi-empirical simulation study shows that the pocket size, about 5 Å, formed by tripodal group is larger than the van der Waals radii of silver ion (about 3 Å), 22 suggesting a loose binding at the pore. It may explain a sub-Nernstian behavior of the compound 1-based membrane.…”

“…The few information available on the coordination chemistry of L 37 (only the X-ray crystal structure of the following complexes are known: [Ag(L)] n (CF 3 CO 2 ) n •nH 2 O, 38 [Ag (L)] n (NO 3 ) n , 39 [Cu(L)](NO 3 ) 2 , 38 [Hg(L)Cl]NO 3 40 and [Ni 2 (L) 2 Cl 2 ]…”

“…In fact, in the case of L 1 , only the X-ray crystal structure of the neutral complex [Cu(L 1 )Cl2] is known [34], while for L 3 , only the 1:1 complex cations [Cu(L 3 )] 2+ and [Zn(L 3 )] 2+ have been reported as nitrate salts [13]. In the case of L 2 , the polymeric complexes [Ag(L 2 )]n(CF3CO2)n•nH2O [35] and [Ag(L 2 )]n(NO3)n [36] were structurally characterized along with the discrete 1:1 complex cations [Cu(L 2 )] 2+ [35] and [Hg(L 2 )Cl] + [37] (NO3and HgCl3 -counter-anions, respectively), and the binuclear compound [Ni2(L 2 )2Cl2](BF4)2•1.5MeNO2 [22]. In fact, in the case of L 1 , only the X-ray crystal structure of the neutral complex [Cu(L 1 )Cl 2 ] is known [34], while for L 3 , only the 1:1 complex cations [Cu(L 3 )] 2+ and [Zn(L 3 )] 2+ have been reported as nitrate salts [13].…”

“…The tendency of the LPs on the S-donors to occupy exodentate positions pointing out of the ring cavity, with the effect of maximizing the number of gauche placements about the C-S bonds, seems more likely to be responsible for the tilted conformation also observed in the phen analogous of L 1 . In both kinds of macrocyclic ligand, therefore, a conformational change in the aliphatic chains is required upon coordination to bring the lone pair(s) of all donors to adopt endodentate orientations suitable for metal coordination [ 13 , 22 , 32 , 33 , 34 , 35 , 36 , 38 , 39 ].…”
