Properties of Conducting 7,7,8,8-Tetracyano-p-quinodimethane Salts with 1,n-Bisalkane Dication Homologues

1,n-Bisalkane-(TCNQ)m salts are nonstoichiometric with m varying from 3.4 to 4.7 for n=2-7.The conductivity (compressed pellet, four-probe method, in the temperature range 230-310 K) varies with the alkyl chain length of the dications, the highest being 2 S cm-1, for n=4 and m=4.6, with the lowest activation energy (0.033 eV).FT-IR and electronic absorption spectra are presented and discussed.On the basis of the results observed, a possible structure is proposed for these homologous salts.

Bromide Complexes of Sb(III) with the 4,4'-Dimethyl-1,1'-Butanediylbis(pyridinium) Cation: Unexpected Formation of Polymorphs with Complex Cations of Various Nuclearity

Abstract: The reaction of solutions of Sb2O3 and 4,4'-dimethyl-1,1'-butanediylbis(pyridinium) dibromide ((4-MePyC4)Br2) in concentrated HBr affords polymorphs: binuclear (4-MePyC2)[Sb2Br8] (I) or tetranuclear (4-MePyC4)2[Sb4Br16] (II) complexes, depending on the reaction conditions. The structures of the complexes are studied by X-ray structure analysis (CIF files CCDC nos. 2061368 (I) and 2061369 (II)).

Synthesis, thermal stability, crystal structure and optical properties of 1,1′-(1,n-alkanediyl)bis(4-methylpyridinium) bromobismuthates

Four hybrid 1,1′-(1,n-alkanediyl)bis(4-methylpyridinium) bromobismuthates, namely (PiC2)2Bi2Br10 (1), PiC4(H5O2)BiBr6·2H2O (2), (PiC5)2Bi2Br10 (3) and (PiC6)2(H5O2)Bi2Br11 (4), were prepared by a facile solution method. The crystal structures of 1 and 3 contain zero-dimensional Bi2Br10 anion units. A 2-D network structure consisting of {H5O2}[BiBr6]·2H2O interconnected by hydrogen bonds was found in 2 and a 1-D network structure consisting of {H5O2}[Bi2Br11] was observed in 4.

Synthesis of some bischromophoric dyes containing nonabsorbing flexible bridge

Bis-chromophoric dyes (9-68) having nonabsorbing flexible bridges have been synthesised by the condensation of 1,1'-alkylenebis (α/γ picolinium bromides) (1-8) with aromatic aldehydes.
