catena-Poly[[di-μ-aqua-bis[aqua­cobalt(II)]]-bis(μ3-1H-benzimidazole-5,6-dicarboxylato]

The title compound, [Co(2)(C(9)H(4)N(2)O(4))(2)(H(2)O)(4)](n), is a one-dimensional polymeric complex with bridging 1H-benzimidazole-5,6-dicarboxyl-ate and aqua ligands. The Co(II) cation has an octa-hedral coordination environment provided by an NO(5) donor set. Adjacent polymeric chains extended along the [100] direction are linked by O-H⋯O and N-H⋯O hydrogen bonds, generating a three-dimensi...

Poly[μ2-aqua-diaqua­(μ8-3-nitro­benzene-1,2-dicarboxylato)(μ6-3-nitro­benzene-1,2-dicarboxylato)tetra­sodium]

In the title layered coordination polymer, [Na(4)(C(8)H(3)NO(6))(2)(H(2)O)(3)](n), the doubly deprotonated 3-nitro-benzene-1,2-dicarboxyl-ate ligands exhibit μ(8)- and μ(6)-coordination modes to the sodium ions, generating sheets lying parallel to (001). The coordination environments of the sodium ions are distorted octa-hedral, distorted trigonal-bipyramidal and moncapped trigonal-prismatic. O...

The two-phase issue in the O(n) non-linear σ-model: a Monte-Carlo study Our paper [1] has motivated a comment [2] by A. Patrascioiu and E. Seiler which we reply in this note. The remarks in [2] concern three statements that the authors select from our paper: i) " The results for O(8) support the asymptotic freedom scenario ". The authors in [2] argue that at small˜β ≡ β/8 the O(8) is expected t...
