Abstract

In the title compound, [Nb(CH(3)O)(3)(C(5)H(7)O(2))Cl], the Nb(V) atom is coordinated by two O atoms from the chelating acetyl-acetonate ligand, three O atoms from the methano-late groups and one chloride ligand. The octa-hedral environment around niobium is slightly distorted with Nb-O distances in the range 1.8603 (15)-2.1083 (15) Å and an Nb-Cl distance of 2.4693 (9) Å. The O-Nb-O angles vary between 80.74 (6) and 100.82 (7)°, while the trans Cl-Nb-O angle is 167.60 (5)°. There are no hydrogen bonds observed, only an inter-molecular C-H⋯O inter-action.

摘要

在标题化合物[Nb(CH₃O)₃(C₅H₇O₂)Cl]中，Nb(V)原子由螯合乙酰丙酮配体的两个O原子、甲醇盐基团的三个O原子和一个氯配体配位。铌周围的八面体环境略有扭曲，Nb - O距离在1.8603 (15) - 2.1083 (15) Å范围内，Nb - Cl距离为2.4693 (9) Å。O - Nb - O角度在80.74 (6)°至100.82 (7)°之间变化，而反式Cl - Nb - O角度为167.60 (5)°。未观察到氢键，仅存在分子间C - H⋯O相互作用。
