1-D coordination polymers containing benzenedicarboxylate

Synthesis, magnetic, thermal and structural properties of Co(II), Ni(II) and Cu(II) complexes containing isophthalato ligands

“…From previous discussion, it could be concluded that 1, 2 and 5 are polymeric with bis-monodentate ipht, while the other two complexes 3 and 4, contain ipht as a counter ion. All Co(II) and Ni(II) complexes are (pseudo)octahedral, while Cu(II) complexes have square-pyramidal (1 and 5) or distorted octahedral geometry (5). The possible structures are presented in Scheme 1.…”

“…Both Co atoms are in highly distorted octahedral environments due to constraints imposed by the presence of four-and five-membered chelate rings. The bond distances and angles for 6 ( Table 5) are typical for ipht complexes with Co(II) in a distorted octahedral geometry [3,5,59,60]. The dihedral angle between aromatic rings of ipht1 and ipht2 is 78.1(1)°.…”

“…If individual COO groups are considered, a full spectrum of coordination modes from simple bis-monodentate, over combinations of monodentate and chelate, monodentate and bidentate-bridge, etc., to bis-chelate and bisbidentate-bridge is found (for characteristic examples see Refs. [2][3][4][5]). Among reported ipht complexes, the compounds having two differently coordinated ipht are infrequent [3,6 and references therein], and the structures with ipht as a counter ion are uncommon [7 and references therein].…”

Di-μ-homophthalato-κ3O:O′,O′′;κ3O′,O′′:O-bis[aqua(1,10-phenanthroline)zinc(II)]

“…Rigid benzenedicarboxylic acids such as terephthalic acid, isophthalic acid and phthalic acid are versatile ligands which can function in monodentate, bidentate or tridentate modes in metal complexes (Bourne et al, 2001;Chen et al, 2004;Hong & You, 2004;Sun et al, 2001;Thirumurugan & Natarajan, 2004;Xiao & Zhu, 2003;Zhu et al, 2004). Homophthalic acid has an acetic acid group and can function as a flexible organic ligand.…”

Hydrothermal Synthesis, Conversion Reaction, and Crystal Structure of 2-D 2-bromo-1,4-benzenedicarboxylate Copper(II) Complex with 2,2′-bipyridine

“…Network diversity of coordination polymers is currently under intensive exploration due to the important relationship between structures and properties as functional materials [1][2][3][4]. In the system of Cu 2+ / 4,4¢-bipy/salicylic acid, six networks covering 0-D, 1-D, 2-D, and 3-D were successfully constructed due to partly and fully deprotonated properties of the combination of hydroxyl and carboxylic groups [5][6][7], while for binary carboxylic acid, such as benzene-1, 4-dicarboxylic acid, networks with partly deprotonated ligands are sparse.…”
