catena-Poly[[diaquaterbium(III)]-tetrakis(μ2-pyridine-4-carboxylato-κ2 O:O′)-[diaquaterbium(III)]-bis(μ2-pyridine-4-carboxylato-κ2 O:O′)]
The title complex, [Tb(2)(C(6)H(4)NO(2))(6)(H(2)O)(4)](n), was isolated under hydro-thermal conditions using the ligand pyridine-4-carb-oxy-lic acid (HL) and Tb(2)O(3). The deprotonated L(2-) ligands adopt bridging coordination modes. The central Tb(III) atom is bridged by L(2-) ligands, forming a polymeric chain parallel to the a axis. Supra-molecular O-H⋯N inter-actions link the chains, build...
متن کامل2,9-Bis(4-pyridylmethoxy)-1,10-phenanthroline
In the title mol-ecule, C(24)H(18)N(4)O(2), the dihedral angles between the mean plane of the phenanthroline ring system and the pyridine rings are 82.52 (5) and 71.58 (4)°. The dihedral angle between the two pyridine ring planes is 53.54 (6)°. In the crystal structure, there are π-π stacking inter-actions between 1,10-phenanthroline rings, with centroid-centroid distances of 3.6101 (11) and 3....
متن کامل(4-Fluorophenyl)thiourea–1,10-phenanthroline (1/1)
Refluxing a mixture of 1,10-phenanthroline, (4-fluoro-phen-yl)thio-urea and cadmium(II) chloride did not produce the expected mixed-ligand complex but formed a co-crystal of the two ligands, C12H8N2·C7H7FN2S. The asymmetric unit consists of two pairs of the co-crystal mol-ecules. In each (4-fluoro-phen-yl)thio-urea mol-ecule, the planes of the N2CS thio-urea units are almost perpendicular to th...
متن کاملProtonation Thermochemistry of Gaseous 2 , 2 ' - , 4 , 4 ' - and 2 , 4 ' - Bipyridines and 1 , 10 - phenanthroline †
Quantum chemical composite methods G3MP2B3, G3B3, G4MP2 and G4 have been used to calculate enthalpies of formation and gas phase basicities of the title compounds. Comparison of the results with the available experimental heats of formation values reveals correct agreement (to within ≈ 2 kJ/mol) with G3B3 and G4 methods. Systematic errors on the heats of formation of these aromatic molecules ar...
متن کاملDichloridobis(4-methylbenzyl)(1,10-phenanthroline-κ2 N,N′)tin(IV)
The tin(IV) atom in the title compound, [Sn(C(8)H(9))(2)Cl(2)(C(12)H(8)N(2))], is chelated by the N-heterocycle and bonded to two C atoms and two chloride ions in an SnC(2)Cl(2)N(2) octa-hedral coordination environment with the C atoms trans to each other. The dihedral angles between the heterocycle ring system and the benzene rings of the 4-methyl-benzyl groups are 21.20 (12) and 28.71 (11)°.
