Abstract Two novel asymmetric bis-schiff bases, 2-【1,2-bis{［(E)-(2-hydroxyphenyl)ymethylidene］amino}-2-(2-pyridinyl)ethyl】phenol(2a) and 2-【1,2-bis{［(E)-(2-hydroxyphenyl)methylidene］amino}-2-(4-pyridinyl)ethyl】phenol(2b), were synthesized via one-pot method by condensation of sailcylaldehyde and NH3 with 2-aminomethylpyridine or 4-aminomethylpyridine, respectively. The structures were characterized by 1H NMR, 13C NMR, IR and X-ray single crystal diffraction(2b). 2b(CCDC： 1 423 247) belongs to monoclinic system, space group P2(1)/n with a=10.764(3) ， b=9.725(2) ， c=21.934(5) ， β=93.291(9) °， V=2 292.2(9) 3， Dc=1.268 mg·cm-3， Z=4， F(000)=920， μ=0.084 mm-1.
