In the title compound, (C(5)H(7)N(2))(6)[V(10)O(28)]·2H(2)O, the [V(10)O(28)](6-) anion is generated by crystallographic inversion symmetry and each of the five vanadium centres adopts a distorted VO(6) octa-hedral geometry. In the crystal structure, a network of N-H⋯O, N-H⋯(O,O) and O-H⋯O hydrogen bonds helps to establish the packing.

The title complex, [V(2)(C(8)H(7)O(3))(2)O(4)(C(12)H(8)N(2))(2)], is a centrosymmetric dimer formed by two V(V) complex units bridged by two μ(2)-oxido groups. The V(V) atom is six-coordinated by three oxide O atoms, one O atom from a vanillinate ligand and two N atoms from a 1,10-phenanthroline ligand in a significantly distorted octa-hedral geometry. In the crystal structure, weak inter-molec...

This paper gives an account of the R/S statistic and its known properties. I t assesses the adequacy of the asymptotic distribution of the statistic in the case of samples of small and moderate size, and suggests an improved approximation based on the beta distribution. The results indicate that the proposed beta approximation is superior to the asymptotic distribution for practical purposes. H...
