Supermolecular coordination isomers: synthesis and crystal structures of four new one-dimensional copper(i) coordination polymers with 1,3-dithiane

Synthesis and characterization of copper(I) compounds incorporating pyrazole-derived ligands: A study on carbon–carbon coupling reaction

“…The bond lengths of Cu(I) atom to acetonitriles associate also in normal range (ca. 2.00 Å) as reported before [41][42][43]. The anionic PF 6 belongs outside the Cu coordination sphere where the Cu-P PF6 bond length is longer than 5.0 Å indicating no interaction between the two ionic molecules.…”

Triflate anion and ligand influences in silver(i) coordination polymers of four isomeric dipyridyl ketone oximes

“…These chains were formed as a result of a single H-bond between the oxime unit and donor N2 on the pyridyl ring of an adjacent ligand. Interestingly, the individual N py atoms were arranged symmetrically in that they were on (14), C(5)-C(4)-C(6) 120.11 (13), C(8)-C(7)-C(6) 120.09 (13). Individual chains were linked into a 2-D sheet consisting of chains of alternating enantiomers by a T-shaped C-H … p interaction between H11 and the ring containing N1 (Fig.…”

“…5 Judicious choice of organic-linker ligands and transition metal ion nodes has allowed the engineering of a wide variety of coordination networks in recent years. However, the balance between the formations of different coordination networks is often subtle, such that metal-to-ligand ratio, [11][12][13] anion-based interactions 11,12,[14][15][16][17][18][19][20][21][22][23][24] and solvent effects 11,12,14,16,17,19,20,22 can all have an influence on the final structural outcomes. However, the balance between the formations of different coordination networks is often subtle, such that metal-to-ligand ratio, [11][12][13] anion-based interactions 11,12,[14][15][16][17][18][19][20][21][22][23][24] and solvent effects 11,12,14,16,17,…”

“…Selected bond lengths (Å) and angles (u): C(1)-C(6) 1.496(2), C(6)-C(7) 1.498(2), C(6)-O(1) 1.228(2); C(1)-C(6)-C(7) 121.73(13). Thermal ellipsoids are drawn at 50% probability level.…”

Crystal structure of the coordination polymer catena-poly[[[(acetonitrile-κN)copper(I)]-μ3-1,3-dithiolane-κ3 S:S:S′] hexafluoridophosphate]

“…2). Overall, the architecture of CP1 is quite reminiscent of that of the 1D polymeric tetrafluoridoborate salt [Cu(1,3-dithiane)-(MeCN)] n + (Knaust & Keller, 2003). Nevertheless, there is one difference.…”
