Abstract
In the title compound, [Zr(C(11)H(10)NO)(4)]·2C(3)H(7)NO, the Zr(IV) ion is coordinated by four bidentate 5,7-dimethylquinolin-8-olate ligands in a slightly distorted square-anti-prismatic coordination environment. The asymmetric unit also contains two N,N'-dimethyl-formamide (DMF) solvent mol-ecules. In the crystal, a weak C-H⋯O hydrogen bond links the complex mol-ecule to a solvent mol-ecule and weak π-π stacking inter-actions [centroid-centroid distance = 3.671 (3) Å] also occur. One of the DMF solvent mol-ecules 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).
