摘要：

The new, ethynyl-bridged ditopic ligand, 1,2-bis[4'-(4-methylphenyl)-2,2':6'2 "-terpyridin-6-yl]ethyne (L) was prepared and used in the formation of the helical dinclear complex [L{Ru(ttpy)}(2)][PF6](4) (ttpy = 4'-(4-methylphenyl)-2,2':6',2 "-terpyridine), whose crystal structure exhibits pronounced bending of the central ethynyl bridge and whose solution NMR spectra indicate a rapid inversion of helicity at 335 K.
