Supramolecular isomerism of a metallocyclic dipyridyldiamide ligand metal halide system generating isostructural (Hg, Co and Zn) porous materials

“…This contributes to the difference in packing observed in comparison to the previously reported structures, a type of supramolecular isomerism. 2,3,8 The ligands within A, D and E have significantly different conformations to all but one of the reported structures of ligand 1, in which only intermolecular hydrogen bonds are observed (Fig. S27).…”

“…1 With this in mind, we investigated a metal halide and dipyridyldiamide ligand, (Compound 1) N,N 0 -(1,2-phenylene) diisonicotinamide, system which was known to form macrocyclic complexes. 2 We noted that Puddephatt and coworkers had used 1 to synthesise metallocycles with a series of mercury halides which have the potential to be porous. 1f,3 By studying the crystallisation of 1 with transition metals and varying conditions such as solvent, metal, concentration and gel formation, we show that the supramolecular isomerism of metallocyclic compounds can allow for the formation of porous materials.…”

Bulky and Modular 3,3′‐Bipyrazoles as Ligands: Synthesis, Characterization, and Catalytic Activity of Pd Complexes

“…[29][30][31] Compound 4h was arbitrarily chosen as the model complex for preliminary catalytic screening. [32] For comparison, [PdCl 2 (3,3Ј-bpy)] [33] (3,3Ј-bpy = 3,3Ј-bipyrazole) was synthesized and tested in parallel as a benchmark under the same reaction conditions. After optimizing reaction conditions, the oxidations of alkenes with molecular oxygen showed overall good conversions to the corresponding ketones (72-87 %; see Table 1).…”

Complexes of gold(I) with a chiral diphosphine and bis(pyridine) ligands: Isomeric macrocycles and a polymer

“…Several ligands of this type were studied but crystalline complexes suitable for X-ray structure determination were obtained only with the ligands LL = 2 -4 (Chart 1). The related ligands 2 [23][24][25][26][27][28][29][30][31][32][33] and 3 [24,26,28,30,33,[34][35][36][37][38][39][40][41], which contain 4-pyridyl and 3-pyridyl groups respectively, are angular whereas ligand 4 [42][43][44][45][46][47][48][49][50][51] is more linear, though it should be recognized that all of these ligands are flexible and can adapt to several different coordination geometries.…”
