Polyrotaxaned versus Interdigitated Super‐Arrays of Loop‐and‐Chain Strands: Role of the Anion in Formation of Silver(0) Particles

Abstract

Self-assembly of AgX (X -= BF 4 -, ClO 4 -, and NO 3 -) with C 3 -symmetric 1,3,5-tris(isonicotinoyloxyethyl)cyanurate (L) yields 1D loop-and-chain strands. However, the formation of a super-array of strands depends on the nature of the polyatomic anions: BF 4 -and ClO 4 -anions induce 1D polyrotaxaned loop-and-chain strands, whereas NO 3 -anion leads to the formation of 2D-like interdigitated loop-and-chain strands in the crystalline state. Calcination of [Ag 3 (L) 2 ]3X (X -

Two Silver Coordination Network Compounds with Colorful Photoluminescence

“…It is well-known that construction of coordination frameworks rests on various factors, such as solvent system, temperature, organic ligands, metal ions, and ratio of metal and ligand. Halogen atoms as simple ligands can adopt 1-, 2-, 3-, and 4-coordinated geometries, while the closed-shell d 10 electronic configuration of Ag­(I) can adopt 2-, 3-, 4-, and 5-coordinated geometries . Therefore, the structural diversity of Ag­(I)–halogen clusters relatively abundant, including the [AgX] monomeric unit, the rhomboid [Ag 2 X 2 ] dimeric unit, the split stair or zigzag [AgX] chain, the [Ag 2 X 2 ] n zigzag double chains, the [Ag 2 X 2 ] n helical chains, the wavelike [Ag 4 X 4 ] n chains, and the hexagonal prism-shaped [Ag 6 X 6 ] cluster unit …”
