Novel malonate-containing coordination compounds with ligands having N-And NO-donors: Synthesis, structures, and magnetic properties
In our efforts to tune the structures of mixed-ligands malonate-containing coordination compounds, four copper(II) and two high-spin cobalt(II) complexes of formulas [Cu(mal)(H 2O)(dpo)] n (1), [Cu 2(mal) 2(H 2O) 2(dpp)] n · 7nH 2O (2), [Cu 2(mal) 2(H 2O) 2-(bpe)] n · 2nH 2O (3), {[Cu(mal) 2(H 2O) 2][Cu(dien)]} n · 4nH 2O (4)[Co 2(mal) 2(H 2O) 6(dpo)] ·2H 2O(5) and [Co(mal)(H 2O)(phen)] n · 2nH 2O (6) [H 2mal = malonic acid, dpo =4,4'-bipyridine-N,N'-dioxide, dpp = 2,3-bis(pyridyl)pyrazine, bpe =1,2-bis(4-pyridyl)ethylene, dien = diethylenetriamine and phen = 1,10-phenanthroline] have been synthesized and structurally characterized by X-ray diffraction on single crystals. Complexes 1, 2, 4,…
Structural changes in the crystal packing of highly hindered symmetrical vicinal bis-amides
The crystal structures of 1,4-bis(3,5-di-tert-butyl-2-hydroxybenzamido)butane (1) and 1,3-bis(3,5-di-tert-butyl-2-hydroxybenzamido)-2,2-dimethylpropane (2) have being characterized by single crystal X-ray diffraction. Their crystal packing is discussed in terms of the different interactions they exhibit. A brief discussion, based on hydrogen bonds, on the structural features of bis-(3,5-di-tert-butyl-2-hydroxybenzamide) compounds is carried out.
Extending the halogen-bonded supramolecular synthon concept to 1,3,4-oxadiazole derivatives
A series of five crystal structures of 1:1 halogen-bonded complexes were obtained from 4-[5-(4-alkoxyphenyl)-1,3,4-oxadiazole-2-yl]pyridine and 1,3,5-trifluorotriiodobenzene. Electronic structure calculations show that the N(oxadiazole)⋯I interaction in the new synthon is as strong as the classic N(pyridine)⋯I interaction. Oxygen to sulfur atom subsitution on the oxadiazole ring results in a different supramolecular packing where the N(pyridine)⋯I interaction is favored, which could be rationalized by the changes in the molecular electrostatic potential predicted from the theoretical calculations.
Crystal structure analysis of supramolecular arrangements in bis(1-isoquinolinecarboxamide)alkanes and their Ag(i) complexes
A homologous series of bis(1-isoquinolinecarboxamide)alkane derivatives (3a–f) with two to seven carbon atoms in the alkyl bridge and their Ag(I) complexes (4a–f) have been synthesized. Four ligand and five Ag(I) complex crystal structures were obtained by single crystal X-ray diffraction and analyzed in terms of: a) their structural patterns based on intra- and intermolecular hydrogen bonds which were compared to those of bis(2-quinolinecarboxamide)alkanes (1n) and bis(6-quinolinecarboxamide)alkanes (2n) attending to specific geometrical parameters and b) the Ag(I) coordinate bond effect on these patterns and the amide-to-amide hydrogen bonds. The crystal structures of the ligands 3a, 3c, …
New anionic cobalt complexes using highly hindered bis-amides with varying donor abilities as ligands.
Four potential tetradentate ligands of formulae 1,2-bis-(3,5-di-tert-butyl-2-hydroxybenzamido)ethane (H(4)L(1), 1), 1,2-bis-(3,5-di-tert-butyl-2-hydroxybenzamido)propane (H(4)L(2), 2), 1,2-bis-(3,5-di-tert-butyl-2-hydroxybenzamido)benzene (H(4)L(3), 3) and 1,8-bis-(3,5-di-tert-butyl-2-hydroxybenzamido)naphthalene (H(4)L(4), 4) have been prepared and the crystal structures of three of them (1, 3 and 4) determined by single crystal X-ray diffraction. The investigation of their complexing ability toward Co(II) afforded the compounds of formulae [Co(III)(L(3))Na(I)(H(2)O)(2)] (5), [Co(III)(L(n))Li(I)(H(2)O)2] with n = 1 (6), 2 (7) and 3 (8) and [Co(II)(L(4))Li(I)(2)] (9). Complexes 5-8 are squa…
