Özet

The asymmetric unit of the title one-dimensional polymeric compound, {[Co(C10H11O2)(2)(H2O)(3)]center dot 2H(2)O}(n), contains one Co-II cation situated on a centre of inversion, one-half of a coordinating water molecule, one 2,4,6-trimethyl-benzoate (TMB) anion together with one coordinating and one non-coordinating water molecule; the TMB anion acts as a monodentate ligand. In the anion, the carboxylate group is twisted away from the attached benzene ring by 84.9 (2)degrees. The Co-II atom is coordinated by two TMB anions and two water molecules in the basal plane, while another water molecule bridges the Co-II atoms in the axial directions, forming polymeric chains running along [001]. The coordination environment for the Co-II cation is a slightly distorted octahedron. The coordinating and bridging water molecules link to the carboxylate groups via intra-and intermolecular O-H center dot center dot center dot O hydrogen bonds, enclosing S(6) ring motifs, while the coordinating, bridging and non-coordinating water molecules link to the carboxylate groups and the coordinating water molecules link to the non-coordinating water molecules via O-H center dot center dot center dot O hydrogen bonds, enclosing R-2(2)(8) and R-3(3)(8) ring motifs. Weak C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions may further stabilize the crystal structure.
