资源简介：
Self-assembly of an achiral [Cu(L)] complex produced
a homochiral
helical chain [Cu(L)]3·2H2O (1) (L = 2-dimethylaminoethyl(oxamato)). Interestingly, complex 1 obtained in our laboratory exhibits only a left-handed helical
chain without any chiral source. Single-crystal X-ray analysis revealed
the absolute structure and homochirality of its helical chain structure
in the space group of P32. Solid-state
circular dichroism (CD) spectra confirmed the high enantio excess
of the crystals obtained in different synthesis batches. Magnetic
susceptibility measurements reveal a relatively strong intrachain
antiferromagnetic interaction between Cu(II) centers via an oxamato
bridge (J = −74.4 cm–1).
