Abstract
In the crystal structure of the title compound, {[Eu(C8H3O7S)(H2O)5]·0.5C10H8N2O2·3H2O}n, the EuIII 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⋯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.
