Catena-Poly[[[pentaaquaeuropium(III)]-μ-5-sulfonatoisophthalato-κO,O:O,O] 4,4'-bipyridine N,N'-dioxide hemisolvate trihydrate].

ABSTRACT: In the crystal structure of the title compound, {[Eu(C(8)H(3)O(7)S)(H(2)O)(5)]·0.5C(10)H(8)N(2)O(2)·3H(2)O}(n), the Eu(III) coordination polymer displays a ribbon motif as the 5-sulfoisopthalate anion uses one of carboxyl -CO(2) units to chelate to a Eu atom and the other to bind to other two Eu atoms; the sulfonyl -SO(3) 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 mol-ecule lies on an inversion centre and is hydrogen-bonded to the complex network. The coordination geometry of the Eu atom is a monocapped square anti-prism.
