title: Potassium (1-methoxy-carbonyl-2-methyl-prop-2-en-2-yl-idene)azinate.
abstract: In the title compound, K(+)·C(6)H(8)NO(4) (-), the K(+) cations have a coordination number of seven and are surrounded by four bidentate azinate anions. The methyl-ene groups of the anions are always directed towards the coordinated potassium cations. The N-C-C-C torsion angle is 101.2 (2)°. The orthogonal non-conjugated nature of the salt confirms the supposed geometry and reactivity of this compound.
