| Abstract: | Different-metal different-ligand complexes [{Co(Phen)3}2{Co(Phen)(H2O)4}2][{Ge(μ-OH)(μ- Hedp)}6Cl2] (I), [{Cu(Phen)2(H2O)}2(HPhen)2][Ge(μ-OH)(μ-Hedp)]6 · 20H2O (II) (H4Hedp = 1-hydroxyethylidenediphosphonic acid, Phen = 1,10-phenanthroline) were synthesized and studied by X-ray diffraction. According to X-ray diffraction data (CIF files CCDC nos. 1573112 (I), 1573113 (II)), compounds I and II are cation–anion type complexes in which the anions are represented by {[Ge(μ-OH)(μ-Hedp)]6}6– and, in the case of I, two additional Cl– ions, while the cations are [Co(Phen)3]2+, [Co(Phen)(H2O)4]2+ in I and [Cu(Phen)2(H2O)]2+, HPhen+ in II. In the crystals of compounds I and II, the cations, anions, and water molecules are combined by numerous intermolecular hydrogen bonds, giving rise to a 3D network. |
