摘要:
The organic ligand (E)-8-hydroxyquinoline-2-carbaldehyde oxime (H2L) was used to react with Ni(CH3COO)(2)center dot 4H(2)O and NaN(CN)(2) at 100 degrees C to obtain the complex [Ni3Na(HL)(3)(L)(2)](n)center dot 4nCH(3)CN (1). Interestingly, the five ligands in the structure chelate three Ni ions, and the uncoordinated O on the ligand captures one Na+. However, the above scheme remains the same, and after adding isonicotinic acid (ina), it obtained the complex [Ni-4(HL)(4)(L)(2)](2)center dot 2CH(3)CN (2), which eight Ni2+ ions are coordinated by twelve ligands. The component distribution of the complexes in different solutions was measured by electrospray-ionization mass spectrometry (ESI-MS). It was found that the complexes exhibited different component distribution in different solutions. Not only the existence of low-nuclear molecular ion peaks could be monitored, but even higher-nuclear components could also be detected, and the alkali metal ions could be effectively identified. It was indicating that the compounds would assemble differently in different solutions. Surprisingly, homonuclear clusters 2 was providing a basis for further directing the directed synthesis of higher nuclear clusters. (C) 2019 Published by Elsevier Ltd.

摘要:
Gas adsorption within the prototypical amidefunctionalized metal-organic frameworks (MOF) Cu(INAIP) has been thoroughly investigated using a combination of single crystal XRD (SCXRD), solid-state NMR (SSNMR) and computational methods. SCXRD was used to locate the exact gas adsorption sites, whereas VT SSNMR spectra were able to probe the local environment about adsorbed gases across a large temperature range, yielding information on the presence and position of nearby paramagnetic metal centers. Computational methods have identified the various interactions responsible for the adsorption of gas molecules, yielding key insights into the host−gas interactions that are unavailable by direct experimental measurement. A cooperative binding model was found to exist in Cu(INAIP) in which the carbonyl group of the amide plays different roles in the adsorption of specific gas molecules, strengthening our understanding of host-gas interactions and gas adsorption in amide-functionalized MOFs.

摘要:
Reaction of CdCl2 or ZnCl2 center dot 4H(2)O, 5-hydroxyisophthalic acid (5-OHH2IP) as well as 1,5-bis (2-ethylimidazolyl)pentane (BEIP) results in formation of a 1D [Cd(BEIP)(Cl)(2)](n) (1) and 2D [Zn(BEIP)(5-OHIP)](n) (2). X-ray diffraction crystal structure analysis shows that 1 crystallizes in orthorhombic system, space group Pca2(1), while 2 is of monoclinic, space group P2(1)/n with beta=100.542 (4)degrees. In 1, the 1,5-bis (2-ethyl-imidazolyl)pentane links all the Cd atoms into a 1D chain. In 2, the carboxylate group with mu(2)-eta(1):eta(1) coordination mode links metal atoms to give a 1D zigzag chain structure, which forming the 2D layer through Zn-N interactions by BEIP ligands. Finally the 2D layers are further assembled into 3D framework by the H-bond interaction. In addition, the properties of complexes 1 and 2 have been investigated, which exhibit good fluorescence in the solid state at room temperature. And complex 2 shows good photocatalytic activity for the degradation of methyl orange solution. CCDC:1523229, 1; 1523230, 2.
摘要:
Two complexes [Ag(bpy)(H2O)](Hbac) (1) and [Ag-2(bpy)(2)(H2O)(2)](pdc)(H2O)(5) (2) (H(2)bac = benzilic acid, bpy = 4,4 '-bypyridine, H(2)pdc = 2,6-pyridinedicarboxylic acid) have been synthesized and characterized by IR, element analysis, X-ray-single crystal diffraction and TGA. Crystal data for 1: Monoclinic, space group C2/c, alpha = 18.8192(5) a, b = 12.7131(5) a, c = 17.8373(8) a, beta = 95.745(4), V = 4246.1(3) a(3) and Z = 8; 2: Triclinic, space group, P-1, alpha = 8.132(5) a, b = 10.485(6) a, c = 18.026(10) a, alpha = 96.194(10), beta = 91.047(11), gamma = 105.866(10), V = 1468.0(15) a(3) and Z = 2. In complex 1, Ag(I) is coordinated by two discrete 4,4'-bpy ligands and one water molecule and Hbac(-) behaves as a counterpart anion. In the crystal, a 3D network was formed by hydrogen bonds and pi pi face-to-face interactions. In complex 2, Ag(I) is also coordinated by two discrete 4,4'-bpy ligands and one water molecule and pdc(2-) behaves as a counterpart anion, too. In the crystal, a similar 3D network was formed by hydrogen bonds and pi pi face-to-face interactions as well as that of complex 1. The luminescence properties of 1 and 2 have been investigated.
