Reactions of Mn(III) quadridentate schiff base compounds with TCNQ anion to form unusual TCNQ derivatives by alcoholysis

The reactions of Mn(III) quadridentate Schiff base compounds, [Mn(saltmen)(H₂O)]ClO₄ (1; saltmen^2- = N, N′-(1, 1, 2, 2-tetramethylethylene)bis(salicylideneiminato)) and [Mn(naphtmen)(H₂O)]ClO₄ (2; naphtmen^2- = N, N′-(1, 1, 2, 2-tetramethylethylene)bis(naphthylideneiminato)), with LiTCNQ gave three type compounds according to reaction conditions: [Mn(saltmen)(H ₂O)](TCNQ) (3), [Mn(saltmen)(MeOH)(TCNQ-OMe)] (4, TCNQ-OMe ^- = p-(α,α-dicyano-α-methoxytolyl)dicyanomethide), and [Mn(naphtmen)(MeOH)(TCNQA-OMe)] (5, TCNQA-OMe^- = p-(α-cyano-α-methoxy-α-methylamidetolyl)dicyanomethide). Compounds 3 and 4 are distinguishable according to synthetic condition either anaerobic or not. Compound 5 is synthesized in aerobic condition as well as 4. For 4 and 5, unusual addition reactions on the anionic TCNQ molecule occur to form (TCNQ-OMe)^- for 4 and (TCNQA-OMe)^- for 5.
