The Schiff base ligands benzylidene(4-tert-butylphenyl)amine 4-methyl ester (L1), (4-nitrobenzylidene)(4-tert-butylphenyl)amine (L2), and (4-cyanobenzylidene)(4-tert-butylphenyl)amine (L3) the new series of cyclometalated mononuclear piano-stool complexes [(η5-C5Me5)RhCl(L1)] (1), [(η5-C5Me5)RhCl(L2)] (2), [(η5-C5Me5)RhCl(L3)] (3), [(η5-C5Me5)IrCl(L1)] (4), [(η5-C5Me5)IrCl(L2)] (5), [(η5-C5Me5)IrCl(L3)] (6) have been synthesized. L1–L3 1–6 thoroughly characterized by satisfactory elemental...
Three new lanthanide metal-organic frameworks IRHs-(1-3) supported by cyamelurate linkers have been synthesized and structurally characterized. The incorporation of numerous heteroatoms (N O) into the pore walls relatively small microchannels these porous solids enhance bonding force host-guest interactions, thus promoting adsorption carbon dioxide (CO2) over methane (CH4). nonpolar covalent bonds in also favor less uptake due to hydrophilic frameworks. Grand canonical Monte Carlo...
A wide range of 4,6-diarylated-2(1<italic>H</italic>)-one derivatives were synthesized in excellent yields from chalcones one pot. Further the designed 4,6-diarylated pyridin-2(1<italic>H</italic>)-one have been successfully utilized synthesizing 2,4,6-triarylpyridines.
Two new ligands N,N,N′,N′-tetraisopropyl/tetraisobutyl-3,4-pyridinedicarboxamide L1–L2 and six of their Hg(II)X2 complexes (where X = Cl–, Br–, I–) have been synthesized characterized. Single crystal X-ray structures three L1 (1–3) with HgCl2/Br2/I2 two L2 (4–5) HgCl2/Br2 show that these are two-dimensional (2D) coordination polymers, different (one new) topologies five coordinated Hg(II) ions, in square pyramidal coordination. Complex 6, HgI2, is a dimer four tetrahedral ion. The behave as...
Interesting correlation between various analytical techniques has been made in this work concerning new isostructural CPs.
A new synthetic route was carried out via a one-pot reaction to prepare novel series of amidine/amidinate cobalt complexes 8-10 by mixing ligand 2 (6-pyridin-2-yl-[1,3,5]-triazine-2,4-diamine) with Co(II) in acetonitrile or benzonitrile. We observed that change solvent from methanol (used complex 7, previously reported) nitrile solvents (MeCN and PhCN) led the situ incorporation amidine group, ultimately forming 8-10. So far, this is unique method reported introduce groups into...
Six supramolecular complexes of charged aliphatic/aromatic amines and polyoxomolybdate anions (β-Mo7O246− β-Mo8O264−) are reported in an effort to study the 'Shrink wrapping' effect these on formation small sized unsymmetrical polyoxomoybdates (POMos). The single crystal X-ray diffraction structures I–II (with tetramethylammonium (TMA+)), III tetraethylammonium (TEA+)), IV tris(2-aminoethyl)ammonium (TREN3+)), V 3-aminopyridinium (AP+)), VI 2-aminomethylpyridinium (AMP+)) as cations, show...

Co-crystals of Co(II) salt and 1H,1′H-[3,3′]bipyridinyl-6,6′-dione 1 with the composition 1·Co(CHOO) 2 (H O) 4 were obtained by mixing both reactants. The single-crystal structure reveals that metal organic ratio is 1:1. supramolecular organization two components in co-crystal was mainly dictated hydrogen bonds between complex. Infrared powder X-ray diffraction used to confirm homogeneity phase purity bulk crystalline sample . TGA/DTA recorded evaluate thermal stability co-crystals.
Dipyridonyl-substituted derivatives 2-4 of benzene, pyridine, and pyrazine, respectively, were synthesized to examine the ability 2-pyridone its protonated species direct self-assembly by hydrogen bonding. Structural analysis single-crystal X-ray diffraction (SCXRD) 2 4 in trifluoroacetic acid demonstrated that salts are formed as a result transfer protons from base (organic species) generate bis(hydroxypyridinium) dication. However, if no proton takes place like case crystals 3 grown...
