Syntheses, structures and vibrational spectroscopy of some 1:1 and 1:2 adducts of silver(I) oxyanion salts with 2,2′-bis(pyridine) chelates

Bis(6‐methylene‐2,2′‐bipyridine)phenylphosphine—A Flexible Ligand for the Construction of Trinuclear Coinage‐Metal Complexes

“…Therefore, the contacts can be described as fully supported metallophilic interactions between the silver and gold cations . This metallophilic interactions may be responsible for the rather strong distortion of the silver coordination sphere compared to [(bipy) 2 Ag]OTf . The metal–metal contacts in compound 4 are similar to those observed in [(Ph 2 PCH 2 PPhCH 2 PPh 2 ) 2 AuAg 2 ](PF 6 ) 3 , in which the distance is 3.0138(4) Å and the metals are also arranged in a linear fashion .…”

Square planar silver(I) complexes: A rare but increasingly observed stereochemistry for silver(I)

“…Benno and Fritchie describe the Ag(I) ion as exhibiting coordination halfway between tetrahedral and square planar. Numerous other complexes containing a similar intermediate Ag(I) stereochemistry have been reported by Bowmaker et al [21], Blake et al [22], and Wu et al [23] An intriguing helical structure containing 16 unique Ag(I) ions with stereochemistries that show a progression from near tetrahedral and becoming increasingly planar has also been reported by Baxter et al [24].…”

“…Colourless crystals of {[Ag(dpk)]ClO 4 } ∞ were obtained from reaction of 2,2 -dipyridylketone (dpk) and AgClO 4 in MeCN [21]. The structure consists of two chemically similar 1D polymer strands.…”

Synthesis and structural characterization of new N2O2-donor Schiff base macrocycles and their silver(I) coordination polymers

“…Considering the intermolecular interactions, the oxygen atoms of the nitrate anion act as hydrogen acceptors, and usually form weak intra/intermolecular C-HÁ Á ÁO interactions with aromatics that stabilize the 3D structure of the coordination polymers [40][41][42][43][44], as the nitrate anion in AgmD1 and AgmD2.…”
