    The title compound, [AlCu3W12O40(C2H8N2)6(H2O)3], was prepared under hydro­thermal conditions. The Cu2+ ion displays an elongated octa­hedral geometry defined by one bridging O atom from the polyoxidoanion and a coordinated water mol­ecule in axial positions and four N atoms of the two chelating ethyl­enediamine (en) ligands in equatorial positions. The one-electron reduced [AlW12O40]6− anion coordinates three [Cu(en)(H2O)]2+ fragments, generating a neutral tri-supported Keggin-type polyoxidometalate (POM). This tri-supported POM is located in a special position of symmetry and therefore O atoms from the central AlO4 tetra­hedron are disordered over two sets of sites. Disorder is also observed for three other bridging O atoms of the POM. In the crystal, mol­ecules are connected via N—H⋯O and O—H⋯O hydrogen bonds, forming a three-dimensional framework

    Large Magnetoresistance over an Extended Temperature Regime in Monophosphides of Tantalum and Niobium

    We report extremely large magnetoresistance (MR) in an extended temperature regime from 1.5 K to 300 K in non-magnetic binary compounds TaP and NbP. TaP exhibits linear MR around 1.8×1041.8\times 10^4 at 2 K in a magnetic field of 9 Tesla, which further follows its linearity up to 1.4×1051.4\times 10^5 in a magnetic field of 56 Tesla at 1.5 K. At room temperature the MR for TaP and NbP follows a power law of the exponent about 1.51.5 with the values larger than 300%300\% in a magnetic field of 9 Tesla. Such large MR in a wide temperature regime is not likely only due to a resonance of the electron-hole balance, but indicates a complicated mechanism underneath.Comment: 13 pages, 4 figures; submitted in May 20, 2015; accepted for publicatio

    Five-dimensional generalized f(R)f(R) gravity with curvature-matter coupling

    The generalized f(R)f(R) gravity with curvature-matter coupling in five-dimensional (5D) spacetime can be established by assuming a hypersurface-orthogonal spacelike Killing vector field of 5D spacetime, and it can be reduced to the 4D formulism of FRW universe. This theory is quite general and can give the corresponding results to the Einstein gravity, f(R)f(R) gravity with both no-coupling and non-minimal coupling in 5D spacetime as special cases, that is, we would give the some new results besides previous ones given by Ref.\cite{60}. Furthermore, in order to get some insight into the effects of this theory on the 4D spacetime, by considering a specific type of models with f1(R)=f2(R)=αRmf_{1}(R)=f_{2}(R)=\alpha R^{m} and B(Lm)=Lm=ρB(L_{m})=L_{m}=-\rho, we not only discuss the constraints on the model parameters mm, nn, but also illustrate the evolutionary trajectories of the scale factor a(t)a(t), the deceleration parameter q(t)q(t) and the scalar field ϵ(t)\epsilon(t), ϕ(t)\phi(t) in the reduced 4D spacetime. The research results show that this type of f(R)f(R) gravity models given by us could explain the current accelerated expansion of our universe without introducing dark energy.Comment: arXiv admin note: text overlap with arXiv:0912.4581, arXiv:gr-qc/0411066 by other author
