The structure and magnetic properties of a 3D pillared-layer polymer and two helical chains constructed from flexible ligands

Three novel coordination polymers of CoII and CuII with flexible ligands, namely [Co(oba)(dpa)]n (1), [Cu(oba)(dpa)]n (2) and [Cu(oba)(bpy)1/2]n (3) [H2oba = 4,4?-oxybis(benzoic acid), dpa = 2,2?-dipyridylamine, bpy = 4,4?-bipyridine] were synthesized by hydrothermal reactions and characterized by single-crystal X-ray diffraction, thermogravimetric analyses, elemental analysis and IR spectroscopy. X-ray diffraction analysis reveals that complexes 1 and 2 are isostructural. In complexes 1 and 2, the CoII and CuII ions are linked by flexible oba ligands to form 1D helical chain. These chains are further assembled into 3D supramolecular edifice via aromatic pi-pi stacking interactions and intermolecular hydrogen bonding. The CuII ions in complex 3 are linked by the carboxylate groups oba to form an eight-membered ring chains, the connectivity between the corner-shared eight-membered ring chains are further bridged by the bent oba ligands to produce 2D helical layer containing the right-handed helical chains. Furthermore, the adjacent helical layers are connected by bpy pillars to form a novel 3D framework with an unprecedented topology of (315¡¤420¡¤58¡¤62). The magnetic properties of complexes 1-3 have also been investigated.

A novel bonding mode of a deprotonated synanti 2,2?-dipyridylamine ligand to dimethyl aluminium and dimethyl gallium. Synthesis, characterization and X-ray crystal structure of Me2Ga(DPA) (DPA = 2,2?-dipyridylamine)

The reaction of 2,2?-dipyridylamine with R3M (R = CH3, M = Ga, Al) gave the Lewis acid-base adducts Me2Ga(dpa) and Me2Al(dpa) (where dpa is 2,2?dipyridylamide). X-ray analysis showed an unusual structure of dpa- in the formation of a new anti-anti complex Me2Ga(dpa) with extremely short bond distances Ga-N(1) [1.976(3) A] and Ga-N(2) [1.978(3) A]. The gallium atom is in a tetrahedral environment, coordinated to the deprotonated chelating ligand and two methyl groups. The bond distances N(3)-C(5) [1.345(4) A] and N(3)-C(6) [1.347(4) A] are almost identical. The bond angle N(1)-Ga-N(2) [92.0(1)] is 17 smaller than, and C(12)-Ga-N(1) [109.5(2)] is almost equal to, normal tetrahedral angles. These adducts are much less air- and moisture-sensitive than the metal trialkyl. The compounds were characterized by elemental analysis, NMR and mass spectroscopy. The conformation of the dipyridylamide ligand in the bidentate chelate complex is significantly different from that observed for other dipyridylamine complexes. Copyright

New type of single Chain magnet: Pseudo-one-dimensional chain of high-spin Co(II) Exhibiting ferromagnetic intrachain interactions

Two new six-coordinated high-spin Co(II) complexes have been synthesized through the reactions of Co(II) salts with dipyridylamine (dpamH) and 5-nitro-salicylaldehyde (5-NO2-saloH) or 3-methoxy-salicylaldehyde (3-OCH3-saloH) under argon atmosphere: [Co(dpamH)2(5- NO2-salo)]NO3 (1) and [Co(dpamH)2(3-OCH 3-salo)]NO3¡¤1.3 EtOH¡¤0.4H2O (2). According to the crystal packing of compound 1, two coordination cations are linked with two nitrate anions into a cyclic dimeric arrangement via N-H…O and C-H…O hydrogen bonds. In turn, these dimers are assembled into (100) layers through pi-pi stacking interactions between inversion-center related pyridine rings of the dpamH ligands. The crystal packing of compound 2 reveals a 1D assembly consisting solely from the coordination cations, which is formed by pi-pi stacking interactions between pyridine rings of one of the dpamH along the [010] and another 1D assembly of the coordination cations and nitrate anions through the N-H…O hydrogen-bonding interactions along the [001] direction. All complexes were magnetically characterized, and a new approximation method was used to fit the magnetic susceptibility data in the whole temperature range 2-300 K on the basis of an empirical expression which allows the treatment of each cobalt(II) ion in axial symmetry as an effective spin Seff = 1/ 2. In zero-field, dynamic magnetic susceptibility measurements show slow magnetic relaxation below 5.5 K for compound 2. The slow dynamics may originate from the motion of broad domain walls and is characterized by an Arrhenius law with a single energy barrier Deltar/kB = 55(1) K for the [10-1488 Hz] frequency range. In order to reveal the importance of the crystal packing in the SCM behavior, a gentle heating process to 180 C was carried out to remove the solvent molecules. The system, after heating, undergoes a major but not complete collapse of the network retaining to a small percentage its SCM character.
