3-(4-Cyanophenyl)pentane-2,4-dione and its copper(II) complex
The -diketone 3-(4-cyanophenyl)pentane-2,4-dione crystallizes as the enol tautomer 4-(2-hydroxy-4-oxopent-2-en-3-yl)benzonitrile, C12H11NO2, (I), with an intramolecular O—H…O hydrogen bond [O…O = 2.456 (2) Å]. Reaction of (I) with copper acetate monohydrate in the presence of triethylamine leads to the formation of the copper(II) complexbis[3-(4-cyanophenyl)pentane-2,4-dionato-2O,O]copper(II), [Cu(C12H10NO2)2], (II). In the structure of (II), the Cu atom is coordinated by four -diketonate O atoms in a slightly distorted square-planar geometry, with Cu—O distances in the range 1.8946 (11)–1.9092 (11) Å. The nitrile moieties in (II) make it a candidate for reaction with other metal ions to produce supramolecular structures.
