| Abstract: | The structure of the title complex, polydicaesium(I) hexaaquacobalt(II) octaaquatetra‐μ‐citrato‐hexacobalt(II)] dodecahydrate], {Cs2Co(H2O)6]Co6(C6H4O7)4(H2O)8]·12H2O}n, at 100 (1) K is formed by layers of a square two‐dimensional polymer composed of CoII citrate cubanes bridged by magnetically active six‐coordinate CoII cations. The polymer has plane symmetry p4mm in the c‐axis projection. The cubanes reside on sites of crystallographic symmetry , while the bridging CoII centres lie on twofold axes. The basic polymeric unit has a charge of 4?, balanced by two Cs+ and a Co(H2O)6]2+ (symmetry ) cation, which lie in channels between the polymeric layers. Unligated water molecules, of which there are 12 per cubane, enter into an extended intralayer and layer‐bridging hydrogen‐bond pattern, which can be described in detail even though not all of the H atoms of the water molecules were located. |
