| Popis: | The stacked two-dimensional supramolecular compoundcatena-{Co(amp)3Cr(ox)3·6H2O} (amp = 2-picolylamine, ox = oxalate) has been synthesized from the bimolecular approach using hydrogen bonds. It is built from layers in which both Co(amp)3+(D) and Cr(ox)3−(A) ions are bonded in a repeatingDADADA… pattern along theaandcaxes by multiple hydrogen bonds. These layers host a well resolvedR12 dodecameric discrete ring of water clusters built by six independent molecules located around the2ccentrosymmetric Wyckoff positions of theP21/nspace group in which the compound crystallizes. These clusters are ranged along the [001] direction, occupy 733.5 Å3(22.0%) of the unit cell and have a chair conformationvia12 hydrogen bonds. The water molecules of the cluster are linked with stronger hydrogen bonds than those between the cluster and its host, which explains the single continuous step of the dehydration process of the compound. |
