In the title compound, [Hf(C11H10NO)4]·2C3H7NO, the HfIV atom is coordinated by four N,O-donating bidentate 5,7-dimethyl-8-quinolinolate (Ox−) ligands arranged to give a distorted square-antiprismatic coordination polyhedron.The average Hf—O and Hf—N distances are 2.098 and 2.298 Å, respectively, and the average O—Hf—N bite angle In Ground Product (Lighting) is 70.

2°.The crystal packing is controlled 2.5" Strip (Jelly Roll) Patterns by π–π interactions between Ox− ligands of neighbouring molecules, giving rise to a three-dimensional supramolecular grid network.The interplanar distances vary from 3.441 (1) to 3.

509 (1) Å, while the centroid–centroid distances vary from 3.688 (2) to 3.759 (12) Å.A non-classical C—H.

O hydrogen bond is observed between the complex and one of the solvate molecules.
