Synthesis and characterization of Cs(5)P[Mo(4)O(14)(OH)](2).2H(2)O: a new molybdophosphate cluster with face-sharing MoO(6) octahedra.

Within the ever-growing field of (hetero)polyoxometalates, the molybdophosphate system occupies a special place as being one of the most extensively studied and quite well understood systems. Its speciation in aqueous solution as a function of pH and phosphate concentration has been established precisely by various methods such as potentiometric, NMR, Raman, and cyclic voltammetry measurements....

Crystal structure of μ-peroxido-κ4 O 1,O 2:O 1′,O 2′-bis­[(nitrato-κO)(2,2′:6′,2′′-terpyridine-κ3 N,N′,N′′)dioxidouranium(VI)]

In the title dimeric complex, [{UO2(NO3)(C15H11N3)}2O2], a peroxide ion bridges the two uran-yl(VI) [O=U=O](2+) ions. The O-O bond length of the peroxide is 1.485 (6) Å and the mid-point of this bond is located at the inversion centre of the dimer. The U atom exhibits a distorted hexa-gonal-bipyramidal coordination geometry with two uran-yl(VI) O atoms occupying the axial positions and one O at...

Anion-directed crystallization of coordination polymers: syntheses and characterization of Cu(4)(2-pzc)(4)(H(2)O)(8)(Mo(8)O(26)).2H(2)O and Cu(3)(2-pzc)(4)(H(2)O)(2)(V(10)O(28)H(4)).6.5H(2)O (2-pzc = 2-pyrazinecarboxylate).

Two new copper 2-pyrazinecarboxylate (2-pzc) coordination polymers incorporating [Mo(8)O(26)](4-) and [V(10)O(28)H(4)](2-) anions were synthesized and structurally characterized: Cu(4)(2-pzc)(4))(H(2)O)(8)(Mo(8)O(26)).2H(2)O (1) and Cu(3)(2-pzc)(4)(H(2)O)(2)(V(10)O(28)H(4)).6.5H(2)O (2). Crystal data: 1, monoclinic, space group P2(1)/n, a = 11.1547(5) A, b = 13.4149(6) A, c = 15.9633(7) A, beta...

The cardioprotective effects of 4-O-(2″-O-acetyl-6″-O- p-coumaroyl-β-D-glucopyranosyl)-p-coumaric acid (4-ACGC) on chronic heart failure

The 4-ACGC isolated from BP was prepared to investigate the cardioprotective effects on attenuating chronic heart failure in vivo and in vitro. A chronic heart failure (CHF) rat model was established to investigate the cardioprotective effects of 4-ACGC. From this, several cardiac function indexes were recorded. The inflammatory markers including tumor necrosis factor-α (TNF-α), Interleukin-6 (...
