Catena-Poly[[[diaqua-lanthanum(III)]-tetra-kis[?-N-(4-acetamido-phenyl-sulfon-yl)-glycinato]-[diaqua-lanthanum(III)]-bis-[?-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?? and ?-? stacking inter-actions can be neglected with regard to stabilizing the network.
