Intramolecular versus intermolecular exchange pathways in the binuclear complex [Cu2(H2tea)2(4,4′-bipy)](ClO4)2·3H2O (H3tea=triethanolamine and 4,4′-…

Abstract The binuclear copper(II) complex of formula [Cu2(H2tea)2(4,4′-bipy)](ClO4)2·3H2O (1) (H3tea=triethanolamine and 4,4′-bipy=4,4′-bipyridine) has been isolated and characterized by X-ray diffraction. Its structure consists of dinuclear [Cu2(H2tea)2(4,4′-bipy)]2+ cations, uncoordinated perchlorate anions and crystallization water molecules. Each copper atom exhibits a trigonal-bipyramidal environment with the three triethanolamine-oxygen atoms building the equatorial plane, and the triethanolamine-nitrogen and one of the 4,4′-bipy nitrogen atoms defining the three-fold axis. The 4,4′-bipy molecule acts as a bismonodentate bridging ligand, the copper–copper separation across it being 11…
The two-dimensional iron(ii)–thiocyanate–4,4′-bipyridine coordination network
2010
The crystal structures of eight solvates of {Fe(4,4′-bipyridine)2(NCS)2}n have been determined. All of them contain a layered iron–bipyridine–thiocyanate framework formed from approximately square infinite two-dimensional (4,4) iron–bipyridine grids, with the solvent molecules hosted between adjacent layers. All the structures contain the iron(II) centres in the high-spin electronic configuration, and magnetic susceptibility measurements on the toluene and nitrobenzene solvates do not reveal any spin-crossover behaviour.

Two-dimensional assembling of 4,4'-bipyridine and 4,4'-azopyridine bridged iron(II) linear coordination polymers via hydrogen bond
1999
[EN] Novel two-dimensional polymers, [Fe(L-1)(H2O)(2)(NCX)(2)]. L-1 (L-1 =4.4'-bipyridine (bipy)) (1, 2) and [Fe(L-2)(CH3OH)(2)-(NCX)(2)]. L-2 (L-2 =4,4'-azopyridine (azpy)) (3) and X = S (1, 3), Se (2), have been synthesized and characterized by X-ray crystallography. The structures reveal the formation of tranzs-L-bridged [Fe(NCX)(2)(Y)(2)] where Y=H2O, CH3OH linear chains assembled into two-dimensional networks by hydrogen bonds between the uncoordinated ligand L and the coordinated solvent molecules.
Crystal structure of [tris(4,4-bipyridine)]diium bis(1,1,3,3-tetracyano-2-ethoxypropenide) trihydrate
2016
In the title hydrated salt, which was obtained from the hydrothermal reaction between between potassium 1,1,3,3-tetracyano-2-ethoxypropenide and 4,4′-bipyridine in the presence of iron(II) sulfate heptahydrate, the ionic components are linked into a three-dimensional network by C—H⋯N hydrogen bonds.
