The title compound, catena-poly[[caesium(I)-μ-18-crown-6-caesnim(I)-di- μ-2-amidopyridine] toluene], · [{[Cs{2-N(H)C5-H 4N}]2(C12H24O6) ·(C6H5CH3)}∞] or [Cs 2(C5H5N2)2(C 12H24-O6)]·C7H8, crystallizes as a toluene solvate. The polymeric structure is constructed from dimeric amido-bridged Cs2N2 four-membered rings with additional supporting coordination by bridging pyridyl N atoms. Each dimeric unit is linked to the next in the polymeric chain by bridging κ6:κ6 18-crown-6 ether molecules, in which each of the six O atoms bonds to both caesium ions; each caesium is ten-coordinate. The polymer has crystallographic mirror (Cs) symmetry, the mirror running through all the caesium ions, so that there is only one unique amidopyridine ligand and each crown ligand is bisected by the mirror. Consequently, the amide ligands are arranged cis with respect to each other, which is unusual. © 2003 International Union of Crystallography Printed in Great Britain - all rights reserved.
