(C9H7INO • C12H4N4) triclinic PT, a = 7.161(5) A, b = 8.639(5) Ä, c = 17.392(6) A, a 64.96(4)°, ß = 80.64(3)°, y = 76.99(3)°, V = 1075.6 A3, Z = 2, dc = 1.47 Mgm-3. The structure was refined to R — 0.114 for 2022 reflections. It consists of segregated diadic stacks of TCNQ and 4-oxo-iodoquinolinium ions. Interplanar distances in the TCNQ stack are 3.09( 1) A and 3.32(1) A ; 3.37(1) A and 3.55(1) A in the quinolinium stack.

متن کاملNew strong organic acceptors by cycloaddition of TCNE and TCNQ to donor-substituted cyanoalkynes.
Donor-substituted 1,1,2,4,4-pentacyanobuta-1,3-dienes and a cyclohexa-2,5-diene-1,4-diylidene-expanded derivative were prepared by a [2 + 2] cycloaddition of tetracyanoethene (TCNE) or 7,7,8,8-tetracyanoquinodimethane (TCNQ) to anilino-substituted cyanoalkynes, followed by retro-electrocyclisation; they feature intense bathochromically-shifted intramolecular charge-transfer bands and undergo th...

Crystallization from an aqueous methanol system composed of Ni(NO3)2, 2,2'-bipyridine (bpy) and LiTCNQ (TCNQ is 7,7,8,8-tetra-cyano-quinodi-methane) in a 1:3:2 molar ratio yielded single crystals of bis-[tris-(2,2'-bi-pyridine-κ2N,N')nickel(II)] bis-(7,7,8,8-tetra-cyano-quinodi-methane radical anion) bi[7,7,8,8-tetra-cyano-quino-dimethanide] hexa-hydrate, [Ni(C10H8N2)3]2(C24H8N8)(C12H4N4)2·6H2O...
متن کاملOutside rules inside: the role of electron-active substituents in thiophene-based heterophenoquinones.
The biradicaloid vs. quinoidal character of the ground state of thiophene-based heterophenoquinones bearing donor or acceptor groups is investigated. Keeping the conjugation length fixed, namely, the 5,5'-bis(3,5-di-tert-butyl-4-oxo-2,5-cyclohexadiene-1-ylidene)-2,2'-dihydroxy bithiophene backbone, an opposite effect occurs depending on the donating or withdrawing nature of the substituents.
