Poly[(μ6-4-amino-3,5,6-trichloro-pyridine-2-carboxyl-ato)aqua-caesium].

ABSTRACT: In the structure of the title complex, [Cs(C6H2Cl3N2O2)(H2O)] n , the caesium salt of the commercial herbicide picloram, the Cs(+) cation lies on a crystallographic mirror plane, which also contains the coordinating water mol-ecule and all non-H atoms of the 4-amino-3,5,6-trichloro-picolinate anion except the carboxyl-ate O-atom donors. The irregular CsCl4O5 coordination polyhedron comprises chlorine donors from the ortho-related ring substituents of the picloramate ligand in a bidentate chelate mode, with a third chlorine bridging [Cs-Cl range 3.6052 (11)-3.7151 (11) Å] as well as a bidentate chelate carboxyl-ate group giving sheets extending parallel to (010). A three-dimensional coordination polymer structure is generated through the carboxyl-ate group, which also bridges the sheets dow
