dc.description.abstract | The title compound, Rb-2[Co(H2O)(6)](C8H5O4)(4)center dot 4H(2)O, consists of nearly regular octahedral [Co(H2O)(6)](2+) cations with the Co-II cations on the inversion centre (special position 2a), Rb+ cations, hydrogen phthalate (Hpht ) anions and disordered water molecules. The Rb+ cation is surrounded by nine O atoms from Hpht anions and water molecules, with a strongly deformed pentagonal-bipyramidal geometry and one apex split into three positions. The crystal packing is governed by numerous hydrogen bonds involving all water molecules and Hpht(-) anions. In this way, layers parallel to the ab plane are formed, with the aromatic rings of the Hpht(-) anions esentially directed along the c axis. While Hpht(-) anions form the outer part of the layers, disordered water molecules and Rb+ cations alternate with [Co(H2O)(6)](2+) cations in the inner parts. The only interactions between the layers are van der Waals forces between the atoms of the aromatic rings. A search of the Cambridge Structural Database for coordination modes and types of hydrogen-bonding interaction of the Hpht(-) anion showed that, when uncoordinated Hpht(-) anions are present, compounds with intermolecular hydrogen bonds are more numerous than compounds with intramolecular hydrogen bonds. For coordinated Hpht(-) anions, chelating and bridging anions are almost equally common, while monodentate anions are relatively scarce. The same coordination modes appear for Hpht(-) anions with or without intramolecular hydrogen bonds, although intramolecular hydrogen bonds are less common. | en |
