In the title compound, [Hf(C(9)H(6)NO)(4)]·2C(7)H(8), the hafnium metal centre is coordinated by four N,O-donating bidentate quinolin-8-olate ligands arranged to give a square-anti-prismatic coordination polyhedron with a slightly distorted dodeca-hedral geometry. The average Hf-O and Hf-N distances are 2.096 (3) and 2.398 (3) Å, respectively, and the average O-Hf-N bite angle is 70.99 (11)°. The crystal packing is controlled by π-π inter-actions between quinoline ligands of neighbouring mol-ecu ...[more]
