Tetrakis(quinolin-8-olato-κ2N,O)hafnium(IV) toluene disolvate

Tetrakis(quinolin-8-olato-κ2N,O)hafnium(IV) toluene disolvate

In the title compound, [Hf(C9H6NO)4]·2C7H8, the hafnium metal centre is coordinated by four N,O-donating bidentate quinolin-8-olate ligands arranged to give a square-antiprismatic coordination polyhedron with a slightly distorted dodecahedral geometry. The average Hf—O and...
