catena-Poly[[tetra-kis-(μ-3,4,5-tri-meth-oxy-benzoato-κ2O:O′)diruthenium(II,III)(Ru—Ru)]-μ-chlorido] with an unknown solvent

摘要

[Ru 2 Cl{ μ -O 2 CC 6 H 2 -3,4,5-(OMe) 3 } 4 ] n was prepared by the reaction of [Ru 2 Cl( μ -O 2 CCH 3 ] n with 3,4,5-tri-meth-oxy-benzoic acid. The complex shows a paddlewheel structure with pairs of Ru atoms bridged by four carboxyl-ate ligands. The axial positions are occupied by shared chloride ions giving zigzag chains. These chains are disposed parallel to each other to give a three-dimensional arrangement packed only by van der Waals forces. The final refinement shows high values of residual non-modelled electronic density. Therefore, the SQUEEZE utility [Spek (2015 ). Acta Cryst. C 71 , 9–18] was used to remove its contribution to the overal intensity data. The electron density modelled by SQUEEZE is consistent with around eight water mol-ecules per unit cell.
