Chlorido-bridged chain complexes of dinuclear ruthenium benzoate analogues, [Ru23,4,5-(CmH2m+1O)3C6H2CO2}4Cl]n (mCl) (m = 3, 5–7, 9, 11, 13, 15, 17), were synthesised and the crystal structure of 3Cl · 2nH2O was revealed. The magnetic measurements for a series of the complexes mCl (m = 2–18) revealed that all the complexes show an antiferromagnetic interaction between the dinuclear unit, with a fastener effect giving the stronger interaction as the alkyl-chain length m increases.
A star-shaped oligobenzoate with short peripheral propyloxy chains (1) forms single crystals 1· (Me2CO)0.5 with a triclinic unit cell from acetone. The oligobenzoate arms are fully extended, possessing only carboxy groups with s-trans conformation. Aliphatic chains and oligobenzoate scaffold do not nano-segregate as proposed for other derivatives which assemble in liquid crystalline phases, but instead, the polar arms occupy the voids between arms of neighboring stars. Although a model based on this scenario may rationalize the small column diameter in the LC phase of longchain derivatives, the low density of the resulting material points rather to the recently established representation with folded conformers self-assembling in columns by nano-segregation.
