In the crystal of the title compound, C(8)H(8)NO(4) (+)·NO(3) (-)·2H(2)O, the 5-ammonio-isophthalic acid cations, the nitrate anions and the water mol-ecules are linked by N-H⋯O, O-H⋯O and C-H ⋯O hydrogen bonds into a three-dimensional network. The structure is further stabilized by aromatic π-π stacking inter-actions, with centroid-centroid separations of 3.827 (2) Å.

The title compound, [Zn(C(8)H(4)O(4))(C(13)H(14)N(2))](n), was obtained by the hydro-thermal reaction of Zn(OAc)(2)·H(2)O with 1,3-di-4-pyridylpropane (bpp) and isophthalic acid (H(2)ip). The Zn(II) ion is coordinated by two bpp and two ip ligands in a distorted tetra-hedral environment. Each ligand coordinates in a bridging mode to connect Zn(II) ions into a three-dimensional diamondoid-type s...

A Cd(II) complex based on fluconazole and isophthalate ligands, {[Cd(HFlu)(IPA)(H2O)]·H2O}n (1), (HFlu = fluconazole; H2IPA = isophthalic acid) has been synthesized. Single-crystal X-ray analysis reveals that complex 1 has a 2D network structure including unusual triple hydrogen bonds between hydroxyl and triazolyl groups. The complex has also been characterized by IR, UV/Vis and fluorescence s...

The title compound, C(12)H(14)O(6), a substituted isophthalic acid monoester which was isolated from the lichen Thamnolia vermicularis var. subuliformis, displays intra-molecular carbox-yl-meth-oxy O-H⋯O and hy-droxy-carboxyl O-H⋯O hydrogen-bonding inter-actions. The terminal methyl group of the ethyl ester is disordered over two sets of sites with occupancies of 0.599 (19) and 0.401 (19).

In the title 1:1 co-crystal, C12H10N2·C8H7NO4, the bi-pyridine moiety shows whole-mol-ecule disorder over two sets of sites in a 0.588 (3): 0.412 (3) ratio. In the crystal, the components form hydrogen-bonded sheets linked by N-H⋯O and O-H⋯N inter-actions, which stack along the a axis. A comparison to a related and previously published co-crystal of 5-amino-isophthalic acid and the shorter 4,4'...

The title copper coordination polymer, [Cu(3)(C(8)H(4)O(4))(2)(C(8)H(5)O(4))(2)(C(10)H(8)N(2))(2)](n), was synthesized by reacting Cu(NO(3))(2), isophthalic acid and 1,10-phenanthroline under hydro-thermal conditions. The trinuclear unit presents a central almost planar CuO(4) chromophore with the cation on a symmetry center, and two symmetry-related CuN(2)O(3) groups with the metal centre in a...

Co-crystallization of 5-fluoro-isophthalic acid (H(2)fip) with 4,4'-bipyridine (bipy) leads to the formation of the title compound [(H(2)fip)(bipy)], C(8)H(5)FO(4)·C(10)H(8)N(2), with an acid-base molar ratio of 1:1. The acid and base subunits are arrange alternately in the crystal structure, displaying a wave-like tape motif via inter-molecular O-H⋯N and C-H⋯O hydrogen bonds [carbox-yl-pyridin...

New step-growth graft block copolymers were synthesized. These two-sided comb copolymers consisted of a poly(amic ester) (PAE) backbone and pendant poly(propylene oxide) (PPO) grafts. The copolymers were made via a macromonomer approach, in which the 4,6-bischlorocarbonyl isophthalic acid bis[poly(propylene oxide)] ester macromonomer was synthesized through the reaction of hydroxyl-terminated P...
