Potassium (1-methoxycarbonyl-2-methylprop-2-en-2-ylidene)azinate

Abstract

In the title compound, K+·C6H8NO4−, the K+ cations have a coordination number of seven and are surrounded by four bidentate azinate anions. The methylene 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.
