Effect of anion and ligand ratio in self-assembled silver(I) complexes of 4-(diphenylphosphinomethyl)pyridine and their derivatives with bipyridine ligands

The Variable Binding Modes of Phenylbis(pyrid‐2‐ylmethyl)phosphane and Bis(pyrid‐2‐ylmethyl) Phenylphosphonite with AgI and CuI

“…[8][9][10][11] We have mainly been interested in synthesizing pyridylcontaining phosphinites and phosphonites where the pyridyl is attached at either the 3-or 4-position which precludes the formation of discrete chelating structures. [8,10,12] More recently we have begun studies on deriviates that are attached to the phosphorus in the 2 position. [11,13] Accordingly, the flexible tritopic ligands phenylbis(pyrid-2-ylmethyl)phosphane (1) and bis(pyrid-2-ylmethyl) phenylphosphonite (2), also known as hemilabile ligands because of the presence of a soft phosphane moiety combined with a metal centers through a phosphorus atom while another is terminally bound.…”

Emerging Trends in Coordination Polymers and Metal-Organic Frameworks: Perspectives, Synthesis, Properties and Applications

“…Consequently, the dimensionalities of the structures increase as the radius of the metal increase down the group that is, from calcium to strontium to barium as shown in Figure 5a-5c. These metal cations from the group 2 of the periodic table increase in metal cation size and polarizability leading to increase in dimensionality [10,11]. A ligand in most coordination polymers will formally donate a lone pair of electrons to a metal cation and form a coordination complex by the means of acid/base relationship.…”

Silver coordination complexes of 2-(diphenylphosphinomethyl)aminopyridine with weakly interacting counterions

“…While the sterically less hindered DPAP-2 is important to formation of the large ring, the tfa -ion aids in the formation of the polymer. Although it is not uncommon to isolate structures with coordinating tfa -ions, the formation of the 1-dimensional polymer 3 is attributed to the bridging tfa -ions [24,25,[41][42][43][44][45][46][47].…”

“…The Ag1···N2 distance is 2.804(3) Å, which is 15 ~ 0.5 Å longer than the Ag-N pyridyl distance seen with DPAP-2 and BPMP ligands. The C6 carbon of the pyridyl ring is 3.280(5) Å from the plane of the N3 ring of the 5,5'-dmbpy ligand, which is a typical distance for π-stacking seen in similar structures [24,25,41,45,46].…”
