cyclo-Tetra-μ-oxido-tetra­kis­[(acetyl­acetonato-κ(2) O,O′)bis­(ethano­lato-κO)niobium(V)]

The asymmetric unit of the title tetra­nuclear niobium(V) compound, [Nb(4)(C(2)H(5)O)(8)(C(5)H(7)O(2))(4)O(4)], contains two Nb(V) atoms, two bridging O atoms, two acetyl­acetonate and four ethano­late ligands. Each Nb(V) atom is six-coordinated by the bridging O atoms, two ethano­late and one chela...

description The asymmetric unit of the title tetra­nuclear niobium(V) compound, [Nb(4)(C(2)H(5)O)(8)(C(5)H(7)O(2))(4)O(4)], contains two Nb(V) atoms, two bridging O atoms, two acetyl­acetonate and four ethano­late ligands. Each Nb(V) atom is six-coordinated by the bridging O atoms, two ethano­late and one chelating acetyl­acetonate ligands. The Nb—O distances vary between 1.817 (2) and 2.201 (2) Å and the O—Nb—O angles vary between 78.88 (8) and 102.78 (9)°, illustrating the significant distortion from ideal ocahedral geometry. The rest of the tetra­nuclear unit is generated through an inversion centre. The C atoms of two of the ethano­late mol­ecules are disordered over two sites [occupancy ratio 0.601 (12):0.399 (12)].
