title: Diaqua-tris-[4,4,4-trifluoro-3-oxo-1-(thio-phen-2-yl)but-1-en-1-olato]neodymium(III) acetonitrile monosolvate.
abstract: The title complex, [Nd(C(8)H(4)F(3)O(2)S)(3)(H(2)O)(2)]·CH(3)CN, consists of an Nd(III) ion surrounded by three 4,4,4-trifluoro-3-oxo-1-(thio-phen-2-yl)but-1-en-1-olate ligands, coordinated through the O atoms, and two water mol-ecules. The Nd-O bond lengths range from 2.372 (2) to 2.513 (2) Å. The metal ion displays a coordination number of eight and a square-anti-prismatic coordination geometry. A single uncoordinated acetonitrile mol-ecule is present in the asymmetric unit. Two of the three thio-phene rings are disordered, resulting from a 180° rotation with respect to the β-diketonate moiety. The coordinated water mol-ecules act as hydrogen-bond donors towards the acetonitrile N atom and the β-diketonate O atoms.
