Poly[μ-aqua-μ5-[2-(2,3,6-tri-chloro-phenyl)acetato]-caesium].
In the structure of the title complex, [Cs(C8H4Cl3O2)(H2O)] n , the caesium salt of the commercial herbicide fenac [(2,3,6-tri-chloro-phen-yl)acetic acid], the irregular eight-coordination about Cs(+) comprises a bidentate O:Cl-chelate inter-action involving a carboxyl-ate-O atom and an ortho-related ring-substituted Cl atom, which is also bridging, a triple-bridging carboxyl-ate-O atom and a bridging water mol-ecule. A two-dimensional polymer is generated, lying parallel to (100), within which there are water-carboxyl-ate O-H⋯O hy-dro-gen-bonding inter-actions.
