| Summary: | In the crystal structure of the title compound, {[Eu(C8H3O7S)(H2O)(5)]center dot 0.5C(10)H(8)N(2)O(2)center dot 3H(2)O}(n), the Eu-III coordination polymer displays a ribbon motif as the 5-sulfoisopthalate anion uses one of carboxyl -CO2 units to chelate to a Eu atom and the other to bind to other two Eu atoms; the sulfonyl -SO3 unit is not involved in coordination. Adjacent ribbons are linked by O-H center dot center dot center dot O hydrogen bonds, generating a three-dimensional network. The 4,4'-bipyridine-N,N'-dioxide molecule lies on an inversion centre and is hydrogen-bonded to the complex network. The coordination geometry of the Eu atom is a monocapped square antiprism. |
