Diaquatris[4,4,4-trifluoro-3-oxo-1-(thiophen-2-yl)but-1-en-1-olato]neodymium(III) acetonitrile monosolvate

The title complex, [Nd(C(8)H(4)F(3)O(2)S)(3)(H(2)O)(2)]center dot CH(3)CN, consists of an Nd(III) ion surrounded by three 4,4,4-trifluoro-3-oxo-1-(thiophen-2-yl) but-1-en-1-olate ligands, coordinated through the O atoms, and two water molecules. The Nd-O bond lengths range from 2.372 (2) to 2.513 (2) angstrom. The metal ion displays a coordination number of eight and a squareantiprismatic coordination geometry. A single uncoordinated acetonitrile molecule is present in the asymmetric unit. Two of the three thiophene rings are disordered, resulting from a 180 degrees rotation with respect to the beta-diketonate moiety. The coordinated water molecules act as hydrogen-bond donors towards the acetonitrile N atom and the beta-diketonate O atoms.
