Notizen:
The title complex, [Eu(C6H4O2)3(H2O)2], has a double carboxylate-bridged infinite-chain structure, with one chelating carboxylate group on each Eu ion centre, which also binds to two water molecules to yield an eight-coordinate square-antiprismatic geometry, with Eu—O bond lengths in the range 2.338 (3)–2.594 (3) Å. The pyridine N atoms of the isonicotinate groups do not coordinate to the Eu ions; instead, they direct the formation of EuIII coordination polymers via hydrogen bonding with coordinated water molecules.
