Interactions of a β-dipeptide with monovalent metal cations: crystal structures of (anthranoyl)anthranilic acid and its lithium, sodium and thallium salts☆

Thermal, fluorescence, structural and solution studies of a thallium(I) one-dimensional coordination polymer with 4-aminobenzoate (AB−), [Tl(μ4-AB)]n

“…Our search show that Zn(II), Co(II), Cd(II) [13] and Ag(I) [14] coordination polymers of 4-aminobenzoic acid (HAB) were recently reported and similar coordination polymers of thallium(I) ion with benzoate-derived ligands were reported in the works by Schmidbaur and Wiesbrock [5,6] and by Kristianson [8]. Continuing with our previous work on Tl I coordination polymers [12,[15][16][17][18][19][20][21][22], in this work we wish to report a coordination polymer of Tl(I) with HAB via hydrogen bonds and covalent bonds with thermal, emission and solution studies of this compound.…”

“…Many parameters are involved in the formation of the metal-organic framework (MOF), such as the metal and its possibilities of coordination, the nature of the counteranion, the metal-to-ligand ratio, the flexibility of the organic building blocks, the number and orientation of the coordinating sites in the organic spacers, and the solvent of recrystallization, among others [2]. The Tl I compounds are interesting and frequently discussed in considering the ''stereo-chemical activity'' of valence shell electron lone pairs, potential ability to form metal-metal bonds and also complexes with aromatic hydrocarbons [3][4][5][6][7][8]. From recent structural study of Tl(I) complexes of anthranilates and salicylates [5], it has been argued that polyhapto-aromatic interactions also play an important role in determining the solid state lattices of such compounds.…”

Crystal structure of poly[(μ3-4-amino-1,2,5-oxadiazole-3-hydroxamato)thallium(I)]

“…3-amino-4-methylfurazan (Pibiri et al, 2018) and 4-amino-1,2,5-oxadiazole-3carboxamide oxime (Zhang & Jian, 2009). Tl I complexes with comparable organic ligands have been reported for thallium (anthranoyl)anthranilate (Wiesbrock & Schmidbaur, 2004), thallium(I) 2-amino-benzoate (Wiesbrock & Schmidbaur, 2003), thallium(I) arylcyanoxime (Robertson et al, 2004) [Tl 4 (H 2 O) 2 (anthracene-9-carboxylate) 4 ] (Kumar et al, 2015) (Britton, 2001) and thallium(I) 4-hydroxybenzylidene-4-aminobenzoate (Akhbari et al, 2009).…”

Metal Complexes of Phenyl Glycine-O-Carboxylic Acid: Preparation, Characterization, Electrochemical and Biological Properties

“…Newly formulated neutral ligand phenyl glycine-o-carboxylic acid is derived from anthranilic acid. A literature survey reported that the characterization of complexes of anthranilate ligands manifest different modes of coordination in which carboxylate anion and nitrogen of amine group [1][2][3][4] and both the oxygen of carboxylic acid 5,6 The crystal structure of Lithium, Sodium, Thallium complexes of anthranoylanthranilic acid have meshed through the oxygen of carboxylate group with trihydrate water molecule was described 7 . An azomethine nitrogen and carboxylate oxygen of mannich base 8 and Schiff base [9][10][11] , obtained from anthranilic acid are documented.…”
