Syntheses and characterizations of polymeric silver iodoplumbates, and iodoplumbates with lanthanide complexes

Noncovalent Interactions at Lanthanide Complexes

“…In the crystals of the Ln‐containing Ag‐iodoplumbates [Ln(DMSO) 8 ][Pb 2 Ag 2 I 9 ] [Ln=La ( 58 ), Gd ( 59 ), Tm ( 60 )], a 1D supramolecular polymer is assembled via very short [Pb⋅⋅⋅I, 3.093–3.119 Å; Σ r vdW (Pb⋅⋅⋅I)=4.00 Å] and high directional (∠I−Pb⋅⋅⋅I, 168.29–177.74°) tetrel bonds involving the [Ag 2 Pb 2 I 9 ] n 3n− anionic chains (Scheme 15a) [162] . By contrast, the Pb⋅⋅⋅I distances inside the aggregate [Ag 2 Pb 2 I 9 ] 3− in 58 – 60 are longer, corresponding to a weak tetrel bond with a moderate directionality (∠I−Pb⋅⋅⋅I: 161.13° ( 58 ), 170.20° ( 59 ) and 169.71° ( 60 ) (Scheme 15a), following the same trend as the optical band gaps (E g , eV) of 2.81 ( 58 ), 2.88 ( 59 ) and 2.73 ( 60 ) [162] …”

Heterometal silver/copper(I) modulated thermochromism of two isostructural iodoplumbates

“…To date, besides of a few neutral [Pb 3 I 10 Cu 4 (phen) 2 ] n , PbI 4 Cu 2 (PPh 3 ) 4 , [Bi(phen)I 4 Ag(phen)] n , [PbCu 6 I 8 ](PPh 3 ) 6 , [PbAg 2 (PPh 3 ) 2 I 4 ] n Á [PbI 2 (DMF) 2 ] n and [Pb(bipy)Ag 3 I 5 ] n [8][9][10][11], the reported heterometallic iodobismuthates/iodoplumbates mainly include the clustered [Cu 2 (CH 3 CN) 2 Bi 2 I 10 2 À ], [Bi 4 [10,[12][13][14][15][16][17][18]. Although Pb is a neighboring element of Bi with similar cation size and octahedral coordination character [13,19], their different oxidation states endow them with specific structural buildings and functional features.…”

“…Templated by transition‐metal‐complex [TM(2,2‐bipy) 3 ] 2+ , Yue successfully constructed a series of 2D inorganic‐organic hybrid [Ag 6 I 11 ] 5− layers featuring efficient visible light photocatalytic properties . In addition, solvated metal cations as another kind of template have been gradually employed due to their relative flexibility and stability recently . The introduction of diverse inorganic ions can endow the targeted iodoargentates with desirable and specific properties.…”
