catena-Poly[[[tetra­aqua­neodymium(III)]-di-μ-isonicotinato] chloride]

In the title complex, {[Nd(C(6)H(4)NO(2))(2)(H(2)O)(4)]Cl}(n), the Nd(III) cation is located on a twofold rotation axis and coordinated by four isonicotiniate anions and four water mol­ecules in a distorted square-anti­prismatic geometry. The carboxyl­ate groups of the isonicotinate anions bridge the Nd(III) cations, forming polymeric chains running along the c axis. The Cl(−) anion is located on a twofold rotation axis and is linked to the polymeric chains via O—H⋯Cl hydrogen bonding. Inter­molecular O—H⋯O and O—H⋯N hydrogen bonds are also present in the crystal structure.
