Expanding the 4,4′-bipyridine ligand: Structural variation in {M(pytpy)2}2+ complexes (pytpy=4′-(4-pyridyl)-2,2′:6′,2″-terpyridine, M=Fe, Ni, Ru) and assembly of the hydrogen-bonded, one-dimensional polymer
摘要:
The solid state structures of [Ni(1)(2)][NO3](2) center dot 2MeOH center dot 2H(2)O, [Fe(1)(2)][ClO4](2) center dot 2MeOH center dot 0.5H(2)O, [Ru(1)(2)][PF6](2) and [Ru(1)(2)][PF6] [NO3] (1 = 4 '-(4-pyridyl)-2,2 ':6 ',2 ''-terpyridine) are presented and the structural variation observed for the {M(1)(2)}(2+) unit is discussed. Protonation of the pendant pyridine group in [Ru(1)(2)](2+) leads to the formation of a hydrogen-bonded, one-dimensional polymer [{Ru(1)(H1)}(n)](3n+) exemplifed by the solid-state structure of [{Ru(1)(H1)}{Fe(NCS)(6)} center dot 1.25H(2)O](n).
