摘要：
A novel six-coordinate ruthenium(II) complex 1, formulated as [Ru(bpy)(2)L-b]PF6 center dot C2H5OH (bpy = 2,2'-bipyridine), has been obtained and characterized. Ligand L-b in 1 comes from a chiral bis-Schiff-base ligand L-a which is condensed between sodium(l) salt of D- or L-phenylanine and terephthaldicarboxaldehyde. It is noted that ligand L-a undergoes partial C = N bond cleavage of Schiff-base unit forming a free aldehyde group at one end of phenyl ring, and an unusual proton migration, a C N double-bond shift and subsequent nonchirality at the other end simultaneously in the presence of a ruthenium(II) ion.
