We report a high yielding synthesis of truly monodisperse, thiolate-protected silver clusters via a rationally designed approach. The cluster composition was determined by electrospray ionization (ESI) mass spectrometry to be Ag(7)(DMSA)(4), where DMSA represents meso-2,3-dimercaptosuccinic acid. The Ag(7) thiolate clusters exhibit distinct optical(More)
The glassy state of a two-dimensional (2D) Cd(2+) coordination polymer crystal was prepared by a solvent-free mechanical milling process. The glassy state retains the 2D structure of the crystalline material, albeit with significant distortion, as characterized by synchrotron X-ray analyses and solid-state multinuclear NMR spectroscopy. It transforms to its(More)
We observed an ordered-to-disordered structural transformation in a Cu(2+) coordination polymer and investigated its influence on the proton conductivity. The transformation generated highly mobile proton carriers in the structure. The resulting material exhibited a conductivity greater than 10(-2) S cm(-1) at 130 °C. The structural transformation and the(More)
The employment of pyridine-2,6-dicarboxylic acid (H2pda) and imidazole (im) in the synthesis of Sr(II)-Sm(III) and Sr(II)-Dy(III) coordination polymers has been reported. Seven novel heterometallic coordination polymers of compositions, [Dy3Sr3(pda)7(Hpda)(H2O)9]·6H2O (1), [LnSr(pda)3(H2O)5]·Him·H2O (Ln = Sm(2), Dy(3)), [Ln2Sr(pda)6(H2O)5]·4Him·C2H5OH·nH2O(More)
Eight novel Sr(II)-Ln(III) heteronuclear coordination polymers based on pyridine-2,6-dicarboxylic acid (H2pda) and imidazole (im) ligands, namely, [LnSr(pda)3(H2O)5]·Him·H2O (Ln = Eu (1), Gd (2), Tb (3)), [Ln2Sr(pda)6(H2O)5]·4Him·C2H5OH·nH2O (Ln = Eu (4), n = 5; Gd (5), n = 4), [LnSr(pda)3(H2O)4]·Him·3H2O (Ln = Gd (6), Tb (7)), and(More)
An efficient strategy for the synthesis of a wide variety of coordination complexes has been developed. The synthetic protocol involves a solvothermal in situ metal-ligand reaction of picolinaldehyde, ammonium acetate, and transition-metal ions, leading to the generation of 12 coordination complexes supported by a novel class of substituted(More)
Acute liver failure (ALF) is a fatal condition hallmarked by rapid development. The present study aimed to describe the dynamic alterations of serum proteins associated with ALF development, and to seek for novel biomarkers of ALF. Miniature pigs (n = 38) were employed to establish ALF models by infusing d-galactosamine (GALN, 1.3 g/kg). A total of 1310(More)
The use of pyridine-2,4-dicarboxylic acid (H2 pydc) in the construction of Sr(II) and Sr(II) -M(II) (M=Co, Ni, Zn and Cu) coordination polymers is reported. Eight complexes, that is, [Sr(pydc)H2 O]n (1), [MSr(pydc)2 (H2 O)2 ]n (M=Co (2), Ni (3), Zn (4)), [ZnSr(pydc)2 (H2 O)7 ]n ⋅4 nH2 O (5), [SrCu(pydc)2 ]n (6), [SrCu(pydc)2 (H2 O)3 ]n ⋅2 nH2 O (7), and(More)
The employment of 2-pyridinealdoxime, (py)C(H)NOH, in nickel(II) and manganese(II) carboxylate chemistry under solvothermal conditions is reported. The syntheses, crystal structures and magnetochemical characterization (for two representative compounds) are described for [Ni(6)(O(2)CMe)(6){(py)C(H)NO}(6)].H(2)O (1.H(2)O),(More)
We synthesized a coordination polymer, [EtMeIm][Cu(bpy)(Me2PO4)3], containing an anionic 1-D chain and an ethyl methyl imidazolium cation. The organic cations show fast transport behavior, and the observed ion conductivity is 1.4 × 10-3 S cm-1 at 110 °C. The stability and structure of the material were confirmed by DSC, X-ray adsorption, and long-term AC(More)
