Planochromism of cyanoxime anions: computational and mechanistic studies in solid state and solutions.

ABSTRACT: The benzoylcyanoxime, NC-C(=N-OH)-C(O)-C₆H₅ (later H(BCO)), represents a new ampolydentate ligand that received attention in the light of useful biological properties of its coordination compounds. Colorless H(BCO), upon deprotonation, gains color that depends on the counter-cation and the system in general. Five derivatives of H(BCO), with colorless organic and inorganic mono-cations - Cs, Tl, Ag, N(CH₃)₄ and As(C₆H₅)₄ - were synthesized and characterized by the X-ray analysis, vibrational and electronic spectroscopy. Compounds exhibited unexpected and significant differences in color, both in solid state and in solutions, that were challenging to explain, thereby warranting detailed investigation including high-
