Azine bridged silver coordination polymers: Powder X-ray diffraction route to crystal structure determination of silver benzotriazole

Poly[aqua-μ-1H-1,2,3-benzotriazole-μ-nitrato-nitratodisilver(I)]

“…This ligand is a neutral donor with the nitrate functioning as both ligand and counterion while the single water molecule provides a fourth ligand for one of the silvers. The Ag-N bond distances [2.248 (6) and 2.216 (7) Å ] are within the normal range and compare well to values of 1.996 (15), 1.979 (9) and 2.202 (13) Å for the parent AgBZT (Rajeswaran et al, 2006). The Ag-O bond distances are long, but not unusual for silver complexes (Jaber et al, 1996), ranging from 2.365 (6) to 2.543 (6) Å .…”

“…Several metal complexes of benzotriazole have been reported, although not generally extensively investigated (Reedijk et al, 1979(Reedijk et al, , 1983Meunier-Piret et al, 1976). While silver benzotriazole, AgBZT, has been known since at least 1924 (Elbs et al, 1924), its solid-state structure has only recently been reported (Rajeswaran et al, 2006).…”

The first chelating olefin: Solid-state structure of bis-(η1-4-phenyl-η2-1-butene)silver (I) tetrafluoroborate

“…The terminal carbons of the title complex ligand show the shortest Ag-C bond lengths at 2.401(7) Å , C(10), and 2.408(6) Å C (20), and the distance to the second carbon in this g 2 bond is longer, at 2.546(7) and 2.566(6) Å , which are similar to the Ag-C olefin bonds of 2.410(6) and 2.445(6) Å in the silver coordination polymer of 1,8-diphenylocta-1,3,5,7-tetraene, Fig. 3 [13].…”

“…There is a rich variety of complexing modes ranging from relatively simple dimeric monomers that exhibit good water solubility [18,19] to complexes having particularly poor solubility [20,21]. In most cases, extensive inter-complex bonding between the silver atom and various donor atoms tend to facilitate the formation of extended networks resulting in multidimensional coordination polymers, which become difficult to redissolve in non-coordinating solvents.…”

Synthesis and characterization of 2-aminobenzoimidazolate group 11 coordination polymers: A combined X-ray powder diffraction and 13CP MAS NMR study

“…These evidences have led to intensive investigations of their physico-chemical properties [13], even though very few studies have been performed on their coordination chemistry, especially concerning their deprotonated forms [14].…”
