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¡ªCl range 3.6052 (11)¨C3.7151 (11) ] as well as a bidentate chelate carboxylate group giving sheets extending parallel to (010). A three-dimensional coordination polymer structure is generated through the carboxylate group, which also bridges the sheets down [010]. Within the structure, there are intra-unit water O¡ªH...Ocarboxylate and amine N¡ªH...Npyridine hydrogen-bonding interactions. %U http://scripts.iucr.org/cgi-bin/paper?S1600536812049562
