| fussnote | The compound, 2,4-dimethylpentadienylpotassium tetramethylenediamine, was obtained by reaction of 2,4-dimethylpentadiene with metallic potassium in tetrahydrofuran (THF) in the presence of tetramethylethylenediamine (TMEDA) at -78^oC. Its crystal structure was determined by a low temperature X-ray diffraction study. The crystal is monoclinic with space group P2"1/n, a 11.322(4), b 9.242(3), c 15.956(5) Å, β 106.73(3)^o, and Z = 4. The final R value is 0.055 for 964 observed reflections. The 2,4-dimethylpentadienyl anion adopts the planar U conformation. The potassium cations, each with a chelating TMEDA molecule attached, are linked by bridging anions while the anions are connected to the bridging cations with the average bond distances KC(1,5), KC(2,4) an KC(3), of 3.123, 3.216 and 3.248 Å, respectively, to form a puckered chain. The structure of the complex is compared with those of 2,4-dimethylpentadiene complexes of transition metals and the bonding within the complex is described. |
