title: catena-Poly[[[diaqua-lanthanum(III)]-tetra-kis[μ-N-(4-acetamido-phenyl-sulfon-yl)-glycinato]-[diaqua-lanthanum(III)]-bis-[μ-N-(4-acetamido-phenyl-sulfon-yl)-glycinato]] 4,4'-bipyridine disolvate tetra-deca-hydrate].
abstract: 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 carboxyl-ate 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 tetra-deca-meric water clusters, which inter-act with their surroundings and finally furnish the three-dimensional supra-molecular 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 mol-ecule with a dihedral angle of 33.12 (13)° between the pyridine rings. Owing to the numerous classical hydrogen bonds, the observed weak inter-molecular C-H⋯O, C-H⋯π and π-π stacking inter-actions can be neglected with regard to stabilizing the network.
