Crystal structure of fac-(l,3-diphenylpropane-l,3-dionato)tris(isopro-poxo) isothiocyanatoniobium(V)

Abstract

Crystals of the title compound are triclinic, space group P[1 with combining macron], a= 17.438(7), b= 9.176(3), c= 9.054(3)Å, α= 107.36(5). β= 96.30(5). γ= 62.94(5)°, Z= 2. The structure was solved from diffractometer data by Patterson and Fourier methods, and refined by least-squares calculations to R 0.042 for 1868 independent non-zero reflexions. The complex is monomeric. The six-co-ordinated metal atom is surrounded by the thiocyanate nitrogen atom (Nb–N 2.176 Å), the two oxygen atoms of the dibenzoylmethane (Nb–O 2.087 and 2.083 Å). and the three oxygen atoms of the isopropoxy-groups (Nb–O 1.845, 1.828. and 1.834 Å).
