title: catena-Poly[[[tetra-aqua-samarium(III)]-di-μ-isonicotinato-κO:O'] chloride].
abstract: In the structure of the title compound, {[Sm(C(6)H(4)NO(2))(2)(H(2)O)(4)]Cl}(n), the unique Sm(III) atom lies on a crystallographic twofold axis and is eight-coordinated by four O atoms from four isonicotinate ligands and four water mol-ecules in a slightly distorted square-anti-prismatic coodination environment. The Sm(III) atoms are bridged by two carboxyl-ate groups of two isonicotinate ligands, forming an extended chain along the c-axis direction. These chains are cross-linked through hydrogen bonds, forming a three-dimensional framework, with channels which accommodate the chloride anions.
