Bis(acetyl­acetonato-κ²O,O′)(N,N-dimethyl­amino­ethanol-κ²N,O)zinc(II)

The title crystalline complex, [Zn(C₅H₇O₂)₂(C₄H₁₁NO)], was prepared as a result of our efforts to synthesize ZnO precursors for chemical vapor deposition. Two acetyl­acetonate and one N,N-dimethyl­amino­ethanol ligands are coordinated to the Zn^II atom in a slightly distorted octa­hedral environment.

Redetermination of bis­(2,4-pentane­dionato)­palladium(II)

The crystal structure of the title compound, [Pd(C₅H₇O₂)₂], has been redetermined at 100 K using modern equipment, resulting in improved precision compared to the previous study [Knyazeva et al. (1970). Zh. Strukt. Khim. 11, 938-939]. The new measurements reveal that the plane of the 2,4-penta­nedionate ligand is tilted by 3.4 (1)° with respect to the PdO₄ unit (Pd site symmetry = ). Possible reasons for this bending are examined in terms of previously undiscussed inter­molecular inter­actions.
