Two 2-D layered coordination polymers based on 5-aminoisophthalate and 1,10-phenanthroline

From Discrete Complexes to Metal–Organic Layered Materials: Remarkable Hydrogen Bonding Frameworks

“…5-Aminoisophthalic acid (H 2 aip, Scheme 1) is becoming a ligand with increasing importance in materials science, since it can adopt several coordination modes, associated with the two carboxylate groups and the amino function [13]. Recently, several CPs based on H 2 aip derivatives have been prepared [14][15][16][17]; however, additional research of these materials is crucial, especially concerning post-functionalization procedures and the development of derivatives with different bases, with the main goal of enhancing their applicability in several technological areas, including gas adsorption and photoluminescence.…”

Hydrothermal syntheses, crystal structures, and luminescent properties of two Mn(II) coordination polymers based on carboxylate and imidazole-containing ligands

“…The Mn-O distances range from 2.0699(15) to 2.468(2) and the carboxylate groups are μ 1 : η 1 /η 1 , μ 2 : η 1 /η 1 and μ 1 : η 1 /η 0 , similar to the Mn-O distances of 1 and 2 and coordination modes for carboxylates[42].In 1 and 2, the adjacent Mn…Mn distances are 3.586 Å, 4.472 Å, and 5.003 Å, respectively, similar to [Mn(dpa)(1,10-phen)(H 2 O)] n [Mn…Mn, 3.471 Å], [Mn(dpa)(2,2′-bipy)] n [Mn…Mn, 3.462 Å], [Mn(L)] [Mn…Mn, 3.96 Å], and [Mn(aip)(phen)] n (H 2 aip = 5-aminoisophthalic acid, phen = 1,10-phenanthroline) [Mn⋯Mn, 4.4465 Å][43].…”
