catena-Poly[[[diaqua­lanthanum(III)]-tetra­kis[μ-N-(4-acetamido­phenyl­sulfon­yl)­glycinato]-[diaqua­lanthanum(III)]-bis­[μ-N-(4-acetamido­phenyl­sulfon­yl)­glycinato]] 4,4′-bipyridine disolvate tetra­deca­hydrate]

In the title compound, {[La(2)(C(10)H(11)N(2)O(5)S)(6)(H(2)O)(4)]·2C(10)H(8)N(2)·14H(2)O}(n), the La(III) ions are in a slightly distorted bicapped trigonal prismatic geometry, and are linked by six carboxyl­ate groups in a syn–syn bidentate bridging fashion to form a one-dimensional inorganic–organic alternating linear chain. These polymeric chains generate microchannels extending along [100], and these cavities are occupied by discrete tetra­deca­meric water clusters, which inter­act with their surroundings and finally furnish the three-dimensional supra­molecular network via 15 O—H⋯O, one O—H⋯S, two O—H⋯N and six N—H⋯O classical hydrogen bonds. 4,4-Bipyridine acts as an inserting component and hydrogen-bond acceptor, and it is a nonplanar mol­ecule with a dihedral angle of 33.12 (13)° between the pyridine rings. Owing to the numerous classical hydrogen bonds, the observed weak inter­molecular C—H⋯O, C—H⋯π and π–π stacking inter­actions can be neglected with regard to stabilizing the network.
