摘要：

Triaquatris(3-hydroxybenzoato)neodymium(III) dihydrate, a new type of lanthanide complex with 3- hydroxybenzoic acid, crystallizes in the monoclinic space group C2/c with a = 22.220(8), b = 10.007(6), c = 22.086(8)Å, β = 99.33(3)° and Z = 8. The crystal and molecular structure of the complex has been determined using X-ray diffraction data measured with MoKα radiation. The Nd3+ ion is coordinated to nine oxygen atoms, with Nd-O distances ranging from 2.338(7) to 2.697(6) A. The coordinated oxygen atoms are from three water molecules and six oxygen atoms are from the 3-hydroxybezoate anions. There are three different binding modes for the anion to the Nd3+ ion: mono-, bi-and terdentate. © 1990, Taylor & Francis Group, LLC. All rights reserved.
