title: Bis[tris(ethylenediamine)cobalt(III)] dichlorobis[mu-(1-hydroxyethylidene)diphosphonato(4-)]diruthenium(II,III)(Ru-Ru) chloride trihydrate.
abstract: In the title compound, [Co(C2H8N2)3]2[Ru2(C2H4O7P2)2Cl2]Cl.3H2O, the building unit contains two crystallographically independent dinuclear [Ru2(hedp)2Cl2]5- anions, where hedp [viz. (1-hydroxyethylidene)diphosphonate] serves as a bis-chelating bridging ligand, two types of [Co(en)3]3+ cations, one uncoordinated Cl- anion and five water molecules of crystallization. The [Ru2(hedp)2Cl2]5- anions are connected to one another, forming one-dimensional chains along the a axis. The [Co(en)3]3+ cations are located between these chains and lie across inversion centres. An extensive series of hydrogen bonds lead to the formation of a three-dimensional supramolecular network structure, with channels generated along the [100] direction. The uncoordinated water molecules and Cl- anions reside in these channels.
