The hydrothermal reactions of 5-(benzimidazol-1-ylmethyl)isophthalic acid (H2L) with Zn(II) and Cd(II) salts lead to the formation of the two new complexes [Cd(L)] (1) and [Zn(L)] (2). In the presence of 2-(pyridin-2-yl)-1H-benzimidazole (pybim) as auxiliary ligand, complex [Zn(L)(pybim)] (3) was obtained. Complexes 1–3 have been characterized by single-crystal and powder X-ray diffraction, IR ...

In the title coordination polymer, [Zn(C(8)H(4)O(5))(C(14)H(22)N(4))](n), the Zn(II) cation is coordinated by an O(2)N(2) donor set in a distorted tetra-hedral geometry. The Zn(II) ions are linked by μ(2)-OH-bdc (OH-H(2)bdc = 5-hy-droxy-isophthalic acid) and bbie ligands [bbie = 2,2'-diethyl-1,1'-(butane-1,4-di-yl)diimidazole], forming a two-dimensional layer parallel to the ab plane. The layer...

Self-assembly of a range of carboxylic acids (benzoic acid, dinicotinic acid, nicotinic acid, and isophthalic acid) with the europium complex of 5-nitro-α,α'-bis(DO3Ayl)-m-xylene (where DO3A is 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid) has been explored to establish the thermodynamics of binding in a range of solvent systems and in a range of aqueous buffer solutions. In this system,...

Using a flexible methylenebis(3,5-dimethylpyrazole) ligand (H2MDP) with different aromatic carboxylate ligands, six new complexes {[Cd(H2MDP)(OPh)](H2O)}n (1), {[Cd(H2MDP)(MPh)](H2O)(1/10)}n (2), {[Cd(H2MDP)(PPh)](H2O)(3/2)}n (3), {[Co(H2MDP)(OPh)](H2O)2}n (4), {Co(H2MDP)(MPh)}n (5), {Co(H2MDP)(HBTC)}n (6) (H2OPh = phthalic acid, H2MPh = isophthalic acid, H2PPh = terephthalic acid, H3BTC = benz...

A new complex, [Cu4(HL)4(H2O)14] (1, H3L·HCl = 5-((4-carboxypiperidin-1-yl)methyl) isophthalic acid hydrochloride), has been prepared and characterized by single-crystal X-ray diffraction, elemental analysis, IR spectroscopy and powder X-ray diffraction (PXRD). The result of the X-ray diffraction analysis reveals that the complex crystallizes in monoclinic, space group C2/c and three unique Cu(...

Coordination polymers derived from 5-benzyloxy isophthalic acid (H2BzOip) are rare, with only three reported that do not contain additional bridging ligands, of which two M2(BzOip)2(H2O) (M = Co and Zn) are isomorphous. It was hoped that by varying the solvent system in a reaction between H2BzOip and M(OAc)2 (M = Co and Zn), from water to a water/alcohol mixture, coordination polymers of differ...

The reaction of mercury(II) chloride with 5-amino-2,4,6-triiodo-isophthalic acid in pyridine solution leads to the formation of the title compound, [Hg(C(8)H(2)I(3)NO(4))(C(5)H(5)N)(2)](n). The structure contains a four-coordinate Hg(2+) ion in a distorted tetra-hedral geometry, which lies on a crystallographic twofold axis. The Hg(2+) ion is bonded to two N atoms from two pyridine ligands and ...

Three new lanthanide-organic frameworks {[Ln(L)(OClO3)(H2O)]·0.5H2O}n [Ln = Sm (1), Eu (2), Er (3)] have been prepared by hydrothermal reactions of the corresponding lanthanide oxide (Ln2O3), silver perchlorate (AgClO4) and 5-(imidazol-1-ylmethyl)isophthalic acid. The complexes have been characterized by single-crystal and powder X-ray diffraction, IR spectroscopy, and elemental analyses. In 1–...

Cu(II) and Zn(II) salts react with 5-(1H-benzotriazol-1-ylmethyl)isophthalic acid (H2L) under hydrothermal conditions to yield two new complexes [Cu(L)(DMF)(H2O)] (1) and [Zn(L)] (2) [DMF = N,N-dimethylformamide], which have been characterized by single-crystal and powder Xray diffraction, IR, elemental and thermogravimetric analyses. As a result, 1 shows a chain structure, further linked toget...
