In the crystal structure of the title co-crystal, C25H32N4O2·C8H6O4, isophthalic acid and [propane-1,3-diylbis(piperidine-4,1-di-yl)]bis-(pyridin-4-yl-methanone) mol-ecules are connected into supra-molecular chains aligned along the c axis by O-H⋯N hydrogen bonding. These aggregate into supra-molecular layers oriented parallel to the ac plane by C-H⋯O inter-actions. These layers then stack in a...

A 2D tri-layer compound {[Co(8)(tbip)(6)(H(2)O)(9)(OH)(4)]·12(H(2)O)}(n) (1) (H(2)tbip = 5-tert-butyl isophthalic acid) consisting of novel heptacobaltate clusters and single cobalt centers bridged by tbip(2-) ligands has been hydrothermally synthesized. The complex represents a rare example of a homometallic coordination polymer built up from both heptanuclear metal clusters and single metal c...

Solvothermal reactions between the polyaromatic group containing carboxylic acid pro-ligands 5-{(pyren-1-ylmethyl)amino}isophthalic (H2L1) and 5-{(anthracen-9-ylmethyl)amino}isophthalic (H2L2) with Zn(NO3)2·6H2O led to formation of new 1D coordination polymer [Zn(L1)(NMF)]n (1) four other polymers, [Zn(L1)(DMF)]n (2), [Zn(L1)(4,4′-Bipy)]n (3), [Zn(L2)(DMF)(H2O)2]n·n(H2O) (4) [Zn2(L2)2(DMF)(CH3O...

Reaction of uranyl cations with phthalic (H2pht) or isophthalic (H2ipht) acids under solvohydrothermal conditions was performed in the presence 3d-block metal associated chelating n...

A mixed ligand Cd(II) complex [Cd(IsoPht)(TEA)H2O]·3H2O was synthesized for the first time by using isophthalic acid (H2IsoPht) and tetradentate triethanolamine (TEA) characterized X-ray single-crystal diffraction, FT-IR, thermogravimetric analysis (TGA). This novel crystallizes in triclinic system with P-1 space group distorted monocapped trigonal prismatic geometry. The has seven coordinates ...

The solvothermal reaction of cobalt(II) chloride and 4,4′,4′′-nitrilotribenzoic acid (H3ntb) in dmf employing a modulator based approach leads to the formation neutral framework with formula [Co9(ntb)6(solv)12]n (JUMP-3). Different mono- dicarboxylic acids such as benzoic, phthalic, isophthalic, acetic could be used appropriate trigger toward framework. X-ray crystallography revealed three-dime...

The development of graphene oxide/rare earth complexes luminescent materials is limited due to the strong quenching ability oxide. However, hybrid with pyromellitic acid (PMA) as ligand not only have better performance, but also stronger luminescence intensity. Herein we tested effect carboxylic structure PMA on intensity materials. Phthalic (PA), Isophthalic (i-PA) and Terephthalic (p-PA) are ...
