Abstract : The crystal structure of the potassium salt of the 4,4-dinitro-2-butenamide carbanion was determined by X-ray diffraction. The entire carbanion is essentially planar. The N-C-N bond angle is 120 deg. in spite of an 0-0 distance of only 2.51 A between the nitro groups. The carbanions lie in planar layers 3.0 A apart and are doubly hydrogen bonded into chains within these layers. The potassium cations lie 0.7 A above and below the anion planes. (Author)
