Tetra­kis(5,7-dimethyl­quinolin-8-olato-κ²N,O)zirconium(IV) dimethyl­form­amide disolvate

In the title compound, [Zr(C₁₁H₁₀NO)₄]·2C₃H₇NO, the Zr^IV ion is coordinated by four bidentate 5,7-dimethylquinolin-8-olate ligands in a slightly distorted square-anti­prismatic coordination environment. The asymmetric unit also contains two N,N′-dimethyl­formamide (DMF) solvent mol­ecules. In the crystal, a weak C—H...O hydrogen bond links the complex mol­ecule to a solvent mol­ecule and weak π–π stacking inter­actions [centroid–centroid distance = 3.671 (3) Å] also occur. One of the DMF solvent mol­ecules was refined as disordered over three sets of sites, with refined occupancies in the ratio of 0.391 (9):0.342 (10):0.267 (7).
