4,4′-(Azinodimethylene)dipyridinium bis(tetrafluoroborate) and 4-[(4-pyridylmethylene)hydrazonomethyl]pyridinium perchlorate: two different hydrogen-bonding motifs
摘要:
In the crystal structures of the title compounds, C12H12N4 (2+)center dot 2BF(4)(-), (I), and C12H11N4+center dot ClO4-, (II), respectively, infinite two- and one-dimensional architectures are built up via N-H center dot center dot center dot F [in (I)] and conventional N-H center dot center dot center dot N [in (II)] hydrogen bonding. The N-N single bond in (I) lies on a crystallographic centre of symmetry; as a result, the two pyridinium rings are parallel. In (II), the pyridinium and pyridyl ring planes are inclined with a dihedral angle of 14.45 (3)degrees.

The heterodinuclear complex, of formula [(bpy)(CO)3Re(I)(PCA)Ru(III)(NH3)5]4+, was obtained by bromine oxidation of the [Re(I), Ru(II)] precursor in CH3CN solution; from spectral and electrochemical measurements, the recombination charge-transfer reaction [Re(II), Ru(II) ] --> [Re(I)

The results confirm that self-assembly of FeII, [HgII(SCN)4]2–, and ditopic rodlike bridging ligands L containing 4-pyridyl moieties favors the formation of linear [Fe(μ-L)]n2n+ chains and in situ generated binuclear units [HgII(SCN)3]2(μ-L)}2–. The latter act as bridges between adjacent chains generating robust 2D layers. The [FeIIN6] centers are equatorially surrounded by four NCS– groups
