N,N′-Bis(2,6-dimethylphenyl)pentane-2,4-diiminato-κ2 N,N′]trichlorido(tetrahydrofuran-κO)zirconium

Abstract

The nacnac (pentane-2,4-diiminato) ligand in the title compound, [Zr(C21H25N2)Cl3(C4H8O)], displays a κ2-coordination to the Zr center. Three chlorido ligands and a coordinated tetrahydrofuran (THF) molecule complete the octahedral environment of the metal. Despite the C 2 symmetry observed in the 1H NMR spectrum, the THF molecule is found trans to one of the N atoms of the nacnac ligand. The asymmetric unit contains two molecules. In one THF ligand one C atom and four H atoms are disordered over two sites in the ratio ca 0.58:0.42.
